Current status 17:00:

Initial discussions of proposals to provide open CARME chamber and provide access to near and far detector chambers

We assume that we need to complete all work installing and testing DSSSDs and re-assembling CARME by Feb 2022 in readiness for bakeout. 




Proposal #1

Disconnect far detector chamber section from mid-chamber section
Disconnect DN350CF flange from near detector chamber 

Crane to support near detector chamber and mid-chamber sections

Remove feet of near detector chamber and mid-chamber sections

Install cradle(s) beneath near detector chamber and mid-chamber sections

Use for fork lift to remove cradle(s) + near detector chamber and mid-chamber sections - ML confirms that an appropriate fork lift is available 


Proposal #2 (suggested by ML)

Design and fabricate table plus rails to extend transverse rails of CARME chamber support assembly
The CARME chamber support assembly comprises the 'feet' plus two-stage welded Al frame 

Disconnect far detector chamber section from downstream section
Disconnect DN350CF flange from near detector chamber 

Slide CARME chamber plus upper stage of Al support frame transversely onto table

Use crane to move CARME chamber to work area


Other discussions

Discussed workarounds to enable install of FEE64s (outside ring, upper feedthrough) which currently conflicts with longitudinal beam of gas jet target support frame.


To Do

Edinburgh

- investigate feasibility of proposal #2
- investigate how much space is required to install FEE64s (outside ring, upper feedthrough)
  e.g. by extension of transverse beams of gas jet target support frame, move current assembly outwards from ring c. 20-25cm


GSI

- investigate feasibility of gas jet target support frame changes outlined above e.g. movement of gas/water services, purchase of longer cross beams etc.


Suggest meeting (online) to discuss results of these investigations and continue discussions w/c August 22

Tried changing ADC control register to 0xf in local controls tab -> stops waveform producing data -> no effect on pulser width (slight increase to 160 chn)
fast comparator blanked off (enable disable mask in discriminator control) -> no effect on pulser width
aida05 was ungrounded -> grounded aida05 to the same ground as aida01-04 -> pulser width reduced to 46 chns
Set ADC control register back to 0x0 -> waveforms back -> pulser width reduced to 24 chns
Changed shaping time from 8ms to 1ms -> pulser width increased to 67 chns -> changed back to 8ms shaping time -> returns to 24 chn width
Changed shaping time from 8ms to 2ms -> pulser width increased to 52 chns
Changed shaping time from 2ms to 4ms -> pulser width decreased to 33 chns

Understand the status reports as follows:-
Status bit 3 : White Rabbit decoder detected an error in the received data
Status bit 2 : Firmware registered WR error, no reload of Timestamp
Status bit 0 : White Rabbit decoder reports uncertain of Timestamp information from WR

Avg ring pressure = 4.3 E-10 mbar

Statistics similar to previous check.

15:15

Temperature setpoint = 113 K

Target density is OK for now. S1 vaies between 2E-8 and 3.5E-8 mbar. E4 between 1E-9 and 1E-8 mbar.

Detector motors functioning well. Moving between 23.1 mm and 67.43mm. Move in and move out counters the same. Correlation scalar 8 for detectors moving is seen on aida1

Rutherford rate peak varies between 10^3 peak height when fully in and ~10^2 when fully out. No peak from halo seen in rate.

Beam intensity ~ 1E8

Merger OK

Data rate ~ 1700 kb/sec

Run is Run 87 - started 10:34

Data spy restarted at 15:00 so only include Run87 data.

Leakage current = 3.205 uA

Fee Temperatures OK

System checks OK - wr fails
