      Set all ELOTECH PID temperature controller zones ( channels ) to 50 deg C
      Expect all non-CARME zones to reach temperature set point quickly. There will be a delay for the TCs corresponding to the CARME heaters but the internal CAME TCs 
will respond more slowly- will observe response of CARME TCs over time.

10:54   Vessel P = 3.89e-8 mbar,  RGA P = 1.4e-6 mbar

Vessel continues to pump down. Baking Jacket fully installed and testing of baking begins before leaving on automatic mode for the week. Some baking jacket pieces may need to be re-jigged a little for use in GSI with the interaction chamber but will be fine for this bakeout. Note that due to the valves 'being in the way' the front of the baking volume holds the majority of the heaters

During this testing phase I have noticed the vessel pressure increase slightly even with vessel temperatures of approx 30C. Pvessel = 5.66e-8 mbar currently. 

Automatic mode started 14:06. I will monitor to check everything is okay before letting it run over the weekend 

16:00 I have noticed that two of the thermocouples floating(back) and floating(top) may be damaged as they were giving sharp spikes in temperature. I have just removed these thermocouples so they should just read the picologger temp. The jacket looks like it is holding temperature quite well. I have set the temperature to 35C and am currently waiting for temperatures to equillibriate before putting back into automatic mode. Pvessel = 1.68e-7 mbar

19:00 Temperatures look good, I will begin bakeout tomorrow morning now, so if anything goes wrong its not in the middle of the night. Have a good weekend all!

Bellow (towards CARME) was installed in the gas jet chamber. Attached are some pictures.

11.00 Per https://elog.ph.ed.ac.uk/CARME/170 and https://elog.ph.ed.ac.uk/CARME/171 issues have been identified with the FEE64 carriers and adaptor PCBs

Some additional comments

1) Per https://elog.ph.ed.ac.uk/CARME/170 attachments 6-9 we can see that there are no cable strain reliefs to which we can attach the FEE64 power, RJ45 network and 
timestamp HDMI cabling. It would probably be straightforward to design something which could be attached to the FEE64 carrier side panels. For the time being we will use 
the copper piping of each FEE64 as the nearest, mechanically stable point to which we secure the cabling.

2) Before the skimming of 1x Delron rail yesterday there was a small amount (<1mm say?) of transverse movement of the FEE64 during insertion into the carrier and it is 
not clear why. Small sample of measurements of FEE64 carriers, spacers etc.

Delron adaptor PCB support widths 92.85, 92.87, 92.90
Al DN100CF flange attachment width 92.97, 92.99, 93.01
Al FEE64 carrier spacing rod 93.03, 93.04, 93.03
FEE64 width (w/ 1x c. 2mm skimmed Delron rail) 100.2, 100.2, 100.3 (3 measurements along the length of the 1x FEE64)
FEE64 carrier width 102.8, 103.0 (2 measurements of 1x FEE64 carrier)


probably indicates that the spacing between the FEE64 plates is consistent. There is some variability (~0.1mm) in the Delron adaptor PCB which could affect the relative 
position of the ERNI pins and sockets. Is there some variability in the width of the FEE64s (w/ rails)?

RSS & TD had some success cleaning the COF600 flange surfaces of the staining and residues observed when the downstream COF600 section was opened yesterday  
https://elog.ph.ed.ac.uk/CARME/118

Isopropanol and laboratory tissues were used - most but not all of the staining and the residues were removed.

Tightened all flanges.

Added Pirani gauge and third IE514 to interaction chamber.

Stated pump down. Around 100 mbar on Interaction chamber Pirani gauge very loud metallic noise is heard. Found bellows between CARME and interaction chamber completely pressed flat. CARME and interaction chamber now much closer. Vented immediately. No pictures. Bellows return to normal state.

Repeated slowly and carefully using theodolite laser on reference point on CARME. Found CARME does not move appreciably forward, thus motion must come from interaction chamber frame.

Mounted two feet between CARME and interaction chamber. Pumped down again. Interaction chamber now moves by few mm. No issues with bellows. Left pumping overnight (Thu 4 November)

Found at 1E-6 mbar this morning. Leak tested. Found four minor leaks. Fixed by tightening. 

US + Kosmos installed Be window. Pumping down extremely slowly. 1 mbar per 2 second. Started turbo at 1 mbar. Pumping down overnight. No damage to window.

See attached new plastic free struts and motion of interaction chamber before after pumping. See skull nose.

Assembled feedthrough flange with re-cut 
SS support bracket. M3 vented on the 
sides, M3x30 partly threaded on top. Top 
screws don't touch the 
Macor (by design? See first attachment). 
Macor affixed but has 
some play - good for thermal dilation.

Mounted long wire harness (side flange) on 
top. Unable to get one of the two 
connectors fully in. Unable to get it out 
as well. See last attach, it's a small gap. 
Tested few pins with multimeter - all ok. 
Decided to mount.

No issues mounting. Slowly and carefully 
threaded wires harness in CARME taking 
care not to hit negs.

Slightly concerned about weight of Macor 
connector on wires, but no obvious 
alternative.

Please have a look at attachments and 
comment. Will keep mounting in the 
afternoon.

5 OCTOBER

08:21 Temperatures stable overnight. See attached. Baking continues.
Remember to visually inspect the tent for potential new drafts the next time in Daresbury.
Also remember to check on thermocouple 1-4 status / position.

10:15 Draft caused by section of top blanket collapsing slightly producing a hole at the top-back end of the volume. Only way to remove draft is to power down and shift 
some of the larger blanket sections over to support the collapsed bit. Keith requires temperatures >120C for the vessel average to proceed so heat was powered down and 
jacket reconstructed. See attached photos of the top of the baking volume (Sorry for quality).

Pressure on vessel when baking concluded: 2e-7mbar

13:00 Baking jacket all sorted, temperature set to 60C to equilibrate. New session had to be started as cooling then heating confuses the rates on the baking program. All 
looks good at the moment, will continue to monitor and increase temperature when needed. Automatic mode may be able to be utilised again as rectifying the insulation on 
the 
back has reduced the thermal gradients somewhat. 

Pressure on vessel when baking restarted: 1e-8 mbar
Bumax order has also been delivered

16:00 Monitoring remotely, bakeout has been on automatic for an hour and is currently at 67C. Vessel gradient ~7.5C

17:15 All looks okay, will leave for a few hours now. Temp is 73C, gradient ~8.2C

22:00 Automatic baking to 90C gradient >10C. Ramped to 105C for RE72-1 and 100C for RE72-2. Will leave overnight to stabilise

6 October

9:50 Temperatures stable, increasing to 115C, 105C 

11:20 Temperatures stable, Increasing to 120C, 115C

13:15 Temperatures stable, increasing to 125C, 120C. Vessel average ~115C. 

14:45 Temperatures stable (see attached). Increasing to 130C, 125C. Vessel average~120C

20:16 Temperatures stable, may be getting to edge of how hot we can get. Increasing to 135C, 130C overnight. Vessel average~128C should be sufficient.

7 October

07:30 Temperatures stable, have reached max temperature we can achieve 132C, 128C on RE-72 thermocouples. Vessel average~131C should be sufficient. Temperatures will be 
maintained until Monday when negs can be activated. 

20:30 Temperatures stable (see attached)

8 October

10:30 Temperatures stable

9 October 

8:30 Temoeratures remain stable 

(NOTE: Raspberry Pi internal clock appears to be on GMT, rather than GMT+1 due to daylight saving.)

Baking started on Mon 28 Sep. Due to WiFi connection authorisation expiring, no remote access was possible until
Tue 28 afternoon.

JM found remotely that temperature had increase up to 80 C, and baking had then been shut off due to negative
gradients. Unclear what happened. System was already cooling.

Restarted baking in automatic mode. Baking shut down automatically after few hours. It is likely the automatic
mode was being confused by vessel cooling and being heated at the same time. 

29 SEP

20:30 Switched to manual mode (60 C). Left overnight

---

30 SEPTEMBER

08:10 Temperatures seem stable, but slight temperature gradient across vessel would prevent automatic mode from
working. See attached.
Unclear why RE72-1 let temperature reach 64 C when setpoint is 60 C. May be affected by RE72-2. Not worrying,
but may confuse automatic mode.
Ramped up to 70 C manually.

11:10 Temperatures stable. Ramped to 80 C manually. Gradient in CARME vessel unchanged at ~11 C. See attached.

14:18 Found baking had stopped shortly after last check. One floating thermocouple reported temperatures above 300 C. 
Unclear what happened. Possible fault? See attached. 
Restarted baking manually at 40 C. Waiting for temperature to stablise. Vessel still cooling - cannot activate
automatic mode.

15:00 Temperatures OK. Ramped manually to 50C

18:10 Temperatures stable. Ramped manually to 60 C. Left automatic mode on

20:20 Found temperature setpoint at 66 C. See attached.
Huge spikes in thermocouple 1-4 Floating (side-low). Same thermocouple that reported temperature spikes earlier. May be
faulty or touching heater directly. Seems to happen for T=65 C and above.
Set to manual mode. Temperature setpoint 60 C. Left overnight.
Will ask local people to remove thermocouple 4 from picologger 1 (aka #A0067/395, port 4) to continue.

---

1 OCTOBER

08:00 Temperatures stable. Interesting behaviour of problematic thermocouple 1-4. Trend looks real. Seems to confirm
hypothesis it is touching a heater.
Waiting for DL locals to disconnect it.

09:49 Thermocouple 1-4 disconnected. Increased temperature manually to 75 C / 70 C. 
It appears RE72-1 consistently reports 5C above its set point. It controls 3 heaters vs. 8 heaters controlled by RE72-2. 
This is most likely due to RE72-2 needing greater power output to reach its setpoint, increasing RE72-1 thermocouple
temperature as a result. 
RE72-2 may be doing very little at the moment.
Hopefully placing its setpoint 5 C above will force both heaters to work together. This may decrease temperature
gradients observed in the vessel.

16:20 Increased temperature manually in steps up to 95 / 80 C.
The uneven temperature setpoints associated with the two RE72 appears to have reduced the temperature gradient in the vessel.
Will ramp up to 100 later this evening and leave overnight.
See attached.

22:00 Temperature stable. Rates are showing unphysical rates (too high / too low) and occasionally going all to zero at the
same time. 
Looks like a previously observed bug that I thought had been sorted. Will have to debug again. Does not affect manual mode.
Ramped temperature to 105 / 95 C. Leaving overnight.
See attached.

---

2 OCTOBER

07:58 Temperatures stable. See attached. Slight gradient in CARME vessel (~11 C). Not worrying.
Ramped manually to 115 / 105 C

12:16 Temperatures stable. See attached. Valve temperature at 46 C.
Ramped manually to 125 / 115 C

17:34 Temperatures stable. See attached. We seem to be getting close to the upper limit of what the tent can achieve.
Ramped manually to 135 / 125 C
Will leave overnight.

---

3 OCTOBER

08:32 We have been baking at full power (heaters always on). Temperatures stable. 
Appears to be as high as we can go with this tent configuration.
Will leave in manual mode and monitor throughout the day.
See attached.

17:00 Temperatures stable. No changes from this morning.

21:00 Temperatures stable. See attached. Baking continues overnight.

---

4 OCTOBER

07:30 Found temperatures decreased overnight by around 10 C. See attached. 
We are still baking at full power. Room temperature has not changed.
Most likely explanation is part of the tent giving / moving due to the baking and a draft being developed.
Will keep monitoring during the day.

13:50 Temperatures stable, no changes from last check.

20:22 Temperatures stable. See attached. Leaving overnight.

07:50 Small leaks (near the motors and upper valve) were detected in the tent which were covered with Al foil.

08:10 ML changed the baking temperature to 120 degrees.

09:40 Since the bottom of CARME is cold, due to uneven distribution of heat, baking is stopped.

13:00 Tent was slightly opened from the sides so that the heat can escape.

13:15 NK mounted three 200 W (see red labels in the picture below) and one 40 W (see the yellow label in the picture below) heating jacket on four CF100 flanges. Power cables and thermocouples were taken care of by AK.

14:00 Tent was closed.

14:00-17:00 ML started baking at temperature 80 degrees to check the heat distribution in the tent. Baking was then stopped and will start from Monday.

Attached - thermocouple temperatures (now correct)

12 October 

10:00 Bakeout temperatures stable. Pressure on the backing line is 3e-7mbar which is the lowest we have achieved on the backing line so far. Vessel pressure can't be measured at the moment as temperature exceeds the max operational temperature of 80C. 

14 October

11:30 Bakeout temperatures stable. Slight day/night cycle can be seen and a ~2-3C dip over the weekend, probably due to heating in ETC turning off at night and over the weekend. Vessel average remains ~130C. Pressure in the backing line dropped to 2.5e-7mbar. EU plug Adapters have been delivered, waiting on leads to begin activation of NEG pumps.  

Water flow and dew point sensors have been installed on the outlet and inlet cooling water manifolds respectively.

Outputs indicating good water flow and ambient temperature above the dew point are connected via an interlock box (constructed by Peter Black)
to the USB-controlled ac mains relay which provides remote control of ac mains power to the AIDA FEE64 PSUs.

The interlock box (see attachment 1) has 

1x 24V dc power input (ac mains transformer)
4x sensor inputs (1x dew point, 1x flow and 2x unused, dummy cable inputs)
4x outputs (1x connected to USB-controlled ac mains relay, 3x unused)

When all sensor inputs are OK, 4x yellow LEDs (corresponding to each of the 4x sensor inputs) are illuminated and visible through the transparent
lid of the interlock box - see attachment 2
The USB-controlled ac mains relay yellow 'water' LED is illuminated if interlock is OK - see attachment 3

16 -  41:ee:71  - bottom right detector -  pn bias

All 8 FEEs have been installed in their holders.

The damaged feedthrough does not have the D-connector on the adaptor board inserted into the falnge but the FEE is connected to the adaptor board. 

FEE's were carefully installed, with one person inserting FEE and another making sure FEE was straight and on the correct pin positions. The spring lock on the bottom FEE's have been tightend and zip ties have been placed to make sure they are secured. 

Rack has been populated with cables from the rack to chamber laid out. Cables mostly go above the rack and hang off the large frame. This frame or the CARME frame takes most of the weight of the cables before they are plugged into the FEEs.   

Cables are numbered 1-8. Brown ethernet cables are numbered 1-4, green 5,6 and yellow 7,8. Numbers correspnd to Bottom FEE (1,2), Side bottom FEE (3,4), Side top FEE (5,6), Top FEE (7,8)

4 FEE holders installed on CARME. Mounting procedure devised due to limited working space to install.

Mounting procedure:
>Install FEE holder mounts (image 1) onto feedthrough flange

>Partially make up FEE holders on workbench. Only 3 cylindrical support rods, spring latches and one of the black adaptor card mounts should be attached to aid install. Bolts should be loose to aid install on CARME. 

>Mount FEE holder to flange

>Connect first adaptor card into D connector on feedthrough, then screw adaptor card to black mount. 

>Screw in second black adaptor card mount but do not tighten bolts. Connect second adaptor card to D connector and screw to black mount. 

>Attach remaining cylindrical supports and tighten all bolts.   

Bolts to install FEE holder mount onto flange (M4x25) are 2mm too long for the hole on the flange. Washer were initially used however this prevents adaptor cards being able to be secured onto thier black mounts. Bolts were shortend 2mm by davide to install. 5 shortend bolts remain in addition to thebag of unshortend M4x25 bolts. 

On the nn flange of the bottom detector (non bias pin D-connector) the feedthrough is damaged. Damage may be repairable, to prevent further damage an adaptor card was not plugged into this D-connector. (image 1)

A bias test was performed for the top detector once adaptor cards are installed. First test is the bias test performed prior to adaptor cards being installed, second test was performed after installation of adaptor cards.   

Installing FEEs on the outer side of the ring in the future may have some mechanical conflict with the gas target frame, see attached images. 

Have observed some instances of poor CARME cable management/routing
Attachment 1 - SAES D-2000 ion pump HV cable (netal braid) transiting FEE64 cabling
Attachment 2 - CARME motor controller cable (grey plastic) transiting FEE64 cabling

General check and tidying up required.
