Comments: First laser does not have a red peak at the center, but maybe okay for this shift.
Attaching PSB and GPS screenshots, as we need to monitor them regularly.
At 6:18 to 6:40, we started getting four rings from the PS Booster.  The 1st ring had a fairly low intensity, and the operators later dropped it.  These times were confirmed 
exactly with communication with PS operators.

====================================================

Tom et al. tuned the trigger this evening, before we began the runs.  (Run 82, or Run 83??)

===TRIGGER===

Trigger condition is: E OR HI/ds

We count the CAMAC OR signals as follows: A,B
    A: Which CAMAC module?  Left to right, 1,2,3,4,5
    B: Which module channel? This is the number engraved on the module by the LEMO output.

==E Definition==
All p-n sides of E detector: 
    RAL 109 discrim cable numbers: 4, 5, 7
       => Corresponds to CAMAC OR Numbers 2,2; 2,1; 3,1, respectively.
    
==HI/ds Definition==
All p-n sides of HI detector: 8, 9, 11
    RAL 109 discrim cable numbers 
       => Corresponds to CAMAC OR Numbers 4,3; 4,2; 5,3, respectively.

ds=Downscale; ds factor is 8 = 2^8 = 256

===SCALARS===

0: Ungated
1: Gated
2: dE (n-n) [Cable 3]
3: E (n-n)  [Cable 6]
4: HI (n-n) [Cable 10]
5: Pulser
6: Clock

===DISCUSSION===
The n-n side of the E detector seems to be noisier than the p-n side.  Thus the p-n side is used for the trigger logic, whilst the n-n side is used for the scalar.

However, there seems to be something confusing about using the p-n side for the true trigger but the n-n side for the scalars.  It means we cannot compare the scalars self-
consistently to each other.  That is, the gated or ungated signals do not have a strong correlation with the individual detector scalars.  In principle if we have enough LEMO 
cables and Fan In/Fan Out modules, we should simply propagate the p-n signals to both the trigger (when relevant, i.e. E detector) and the scalars alike.  For now we don't 
touch anything, though.

     Negative: Low freq, 1200 setting.

Scalars 0 and 1 (see https://elog.ph.ed.ac.uk/ISOLDE/49 ) were in at the beginning of the run.  Scalar 2 was added part way through.  LEMO cables were not long enough to add 3 & 
4 until after the run was stopped (swapped short cables for longer ones elsewhere.)

Scalar 0 was showing a number of multiple hits.  It was directly from the Fan In / Fan Out.  At the end of the run, I switched it to the Lecroy 622 which has a larger width.

We stopped because the PS-Booster called about cleaning one of the rings.  (At first I misunderstood exactly what was going on or who called, but I stopped.)

====================================================

Faraday cup readout at the end of our chamber should change based on whether or not the target is in and also the 59Cu beam energy.

The effect could be as much as 10 to 20%.  At some point, we should check the Faraday cup reading with the CH2 target and with the empty target.

*Safety shoes and hard hats are required for everyone.  We need to buy our own in the future and bring them with us.

The 'general purpose scattering chamber' seems to in fact be named the Scattering Experiments Chamber (SEC).
     Contact Joakim Cederkall at Lund University in Sweden joakim.cederkall@cern.ch (DK has collaborated with him before in 2012)
     Secondary contact olof.tendblad@cern.ch

2 meters downstream of SEC we see the SAND neutron detector array.
     Contact Ismael Martel at University of Huelva in Spain ismael.martel.bravo@cern.ch
     Array structure is on wheels, but needs to be moved before our experiment, presumably by someone from that collaboration
          Of course, we don't know after the SEC relocation from station 2 to station 3 that SAND will be installed in the same relative position or not

SEC has eight (8) transverse ports evenly spaced about its circumference
     We need adapters to connect to this
     The nominal ISOLDE beamline pipe is 50 mm diameter
     Chamber itself is about 1 meter in diameter, about 70 cm tall.  Shape is a cylindrical prism with hemispheres on top and bottom
     Calculated volume about 0.55 cubic meters
     Support structure is about 1 x 1 square meter footprint, about 125 cm tall
     2 large-volume pumps in parallel.
          TMP: PTM 5400 ALCATEL CORP x2
          Oil roughing pumps Edwards 12 x2
     According to Karl, its pressure is in the low 10^-6 mbar region, but everything seemed off when we visited so cannot confirm precise value
     Presumably it requires the overhead crane to open it
          Not many people have the license
          Although we don't need to access it very often if at all
          Karl said they are arguing to install a small fixed crane for that purpose after relocation which wouldn't need a license
     SEC is being disconnected over the weekend (21~22 Jan)
         
Alignment in ISOLDE Hall (not very sensible to write w/o diagram)
     POT1, POT2 are on the wall downstream of the beam lines
     POT3 and POTREX are on the beam-right side before it is turned and delivered to the target stations
     Geodetic survey points -- though we don't really know how they are used

Downstream of station 3 (under construction) is XT03 which is a crosshair on the wall
     Presume it was used for alignment of the steering magnet base
          Bases are installed but the quadrupoles are still off to the side

There is no port on the station 2 bending magnet to offer a straight line of sight down to the target station
     How was the alignment performed?
     We assume station 3 will be installed in a similar manner, unfortunately.

Station 3
     Expected to be complete by the end of February

Station 2
     HELIOS-type device will be installed at station 2
     This is presently called ISS and is mainly being done by the Swedish group (Lund?)
     Footprints were drawn on the ground downstream of the present SEC point
     How much space will the fence to prohibit near-approach for B-field safety be?

Distances around the stations
     From the target positions to the far wall is over 10m, though a lot of equipment and storage lines the wall area
     Beam-right wall from station beam-line 3 is about 180 cm
     7 m to station 2 -> ~5 m between station 2 and 3
     End of station #2 to the end of the SEC including the beam pipe is ~210 cm

At some point, we must provide a list of items ot be imported and used so it can be approved by the CERN Safety groups

==Meeting notes with Karl Johnston==

HIE-ISOLDE may begin physics around the last week of June (say 24~25th)
     A MINIBALL experiment is usually prioritized first, given the track record and existing infrastructure and experience.

From the end of April there will be about 2 months of commissioning, ideally
     Though, in years past, the timeline was too tight and commissioning was basically not performed during this period

They will start the cryogenics on Tuesday, 24th January

ISS will start to be installed in May for about 3 weeks (? hand writing and detail of notes is poor on this point)

Anytime in mid-March should be okay for the Edinburgh group to ship

59Cu is a candidate for an early run this year
     As soon as early July perhaps in an ideal world

These are used to connect the gas cell to the target ladder.  We only had the one, and it would be more convenient if each gas cell has its own, to avoid swapping them back and forth.

Drawings attached.
