 Tue Mar 1 12:58:32 2022, CB, MS, SS, ML, Synced pneumatic motion
|
New run R84
Attempting to sync pneumatic movement with ring. Still see something on t out -> p out
Command to move out was being given relative to the wrong time. |
|
Tue Mar 1 16:57:34 2022, CB, LV, PMH, New run
|
Beam issues due to too long storage time in the last hours. Motors moved out and not moving.
Decreased storage time to 70 s. Seems OK now. Restarted motor movement as before
Started new run R86 |
Tue May 27 22:20:11 2025, CB, LB,PW, Run 25 - 1.99/2.02 MeV/A 27x
|
23:20
JM thinks we cannot see 7Be locus on run 24. Possibly the right arm cannot get close enough.
Stopped moving right arm |
|
Sat Jun 8 10:13:52 2024, CB, JM, TD, Run 50/51 - data taking 8x
|
11:13
ML enabled ring signals remotely.
Used FakeMotion.dat (read FakeMotion.dat from InteractiveMotion.x). |
|
Tue Jun 10 09:57:50 2025, CB, JM, PJW, YuL, JG, Run 62
|
10:58
As Run 61, no target for background.
200 keV/A |
|
Thu Jun 12 15:33:17 2025, CB, JM, EM, JG, TD, AB, CF, AR, Run 74 27x
|
16:34
Like Run 73, but particle detector in YR10 now active, and recorded in MBS.
Clear effect of target on beam lifetime. Target off -> nearly no counts. |
|
Thu Oct 29 08:02:29 2020, CB, JM (remotely), CARME pressure
|
Attached is the temperature plot for bakeout period including tags for NEG activation etc.
28 October -> 27 November
|
|
Wed Apr 26 16:49:28 2023, CB, JM, CARME dolly mostly built
|
Disconnected cables from CARME motors and turbo. The turbo has to go to allow Carme to slide out. Crane may be required to lift because it's in a
very hard spot to access.
|
|
Thu Apr 27 19:43:23 2023, CB, JM, Preparing to open
|
Removed turbo pump and set aside in a box. Considering switching to the other turbo to avoid degradation due to lack of use.
Installed bellows support and OG devised support to avoid bellows sagging when Carme is split open. |
|
Sat Apr 29 10:12:58 2023, CB, JM, CARME opened 8x
|
(28 April)
Mounted rails on dolly. The rails don't smoothly connect to those on the Aluminium frame and some thin metal shims were required to get the
correct height. A metal support had to be placed above the Delrin pads to support the rails above the gap between frames. |
|
Sun Apr 30 10:01:39 2023, CB, JM, Left hand detectors unmounted 26x
|
(29 April)
Inspected CARME after opening. See attached. Some key takeaways.
- No visible damage to the detectors or the Kapton cables. No visible deposits or dust on the detectors either. |
|
Mon May 1 08:26:09 2023, CB, JM, Left hand detectors remounted
|
(31 April)
Remounted 3335-12 on top and new 3335-1 on bottom of left hand plate. Used new dog legs and old standoffs.
|
|
Mon May 1 18:21:18 2023, CB, JM, All detectors mounted
|
Mounted four detectors on Carme ad well as four cable harnesses.
Cables for new, shorter harnesses appear still too long. Likely the model is not correct somehow. |
|
Tue May 2 15:02:09 2023, CB, JM, All detectors and harnesses mounted
|
Completed mounting harnesses and detectors.
The strain relief support for the bottom most two detectors on the feedthrough side was not mounted because we could not find enough MACOR parts
and mounting flanges. We cannot find them in GSI, possibly they are somewhere not obvious in Edinburgh. |
|
Thu Jan 4 13:15:10 2024, CB, JM, Tent removed - bias test
|
Removed tent, octagon, Neg cables.
Disconnected and removed Baking Pi, TC08, thermocouples.
Tested new rails, plates, fees - it fits. Need to check on the flange next. |
|
Sun Jan 7 15:38:57 2024, CB, JM, Manifolds mostly assembled + bias overnight check
|
Assembled most of the connectors on the new (green) manifolds. Two blanking pulgs stuck when mounting - cannot remove them or tighten them. Swarf? Will
ask Davide's help tomorrow. Cannot use the manifold until this is fixed.
Checked FEE assembly in cassette. Need to shorten black Delrin supports by ~6 mm. Holes should end up in the correct position thanks to rails |
|
Mon Jan 8 19:27:36 2024, CB, JM, Leak current tests overnight
|
| Left bias in overnight. Leakage current decreased and stabilised. See attached. Bias off as we prepare to mount the fees. |
|
Mon Jan 8 19:29:57 2024, CB, JM, Manifold repaired + fee assembly in bench
|
Davide extracted the stuck blind plugs and re-threaded all missing ports. Completed manifold assembly, except for main inlet/outlet - left for plumber.
Cut 8x2 2m hoses and assembled with Swagelok quikfit and teflon ferrules.
We're missing back ferrules in brass for the repaired fees. It should be possible to buy them from GSI. |
|
Wed Jan 10 10:22:41 2024, CB, JM, Some FEEs mounted - issues with Det#2 (bottom left)
|
Started mounting some FEEs. We ran into some mechanical issues due to the new ERNI connectors on the new flexi-rigid adaptor PCBs. Davide skimmed 6.5
mm off the edge with the groove (the groove is gone). This is suffiicent to support the flexi-rigid and in spite of our earlier concerns, the flexi-rigid
can be mated/un-mated with the FEEs without major alignment issues. |
|
Wed Jan 10 19:27:08 2024, CB, JM, Manifold and more bias tests
|
Mounted water manifold on CARME with help from GSI plumber. Connected all the hoses with Swagelok self-locking connectors. Tested for water leaks - it
leaks from nearly every port. The issue appear to be the connections between the manifold and the plugs, as opposed to the plugs and the hoses which do
not leak. |
