SUMMARY FROM THE DSG (Aaron Brown)
- Much progress! - check the DSG Technical Documentation Webpage for updates
- Cables
- 390 made, can make 200 cables/month
- plan to test all HV cables
- CAEN crates for EPICS
- 32/34 almost done
- WEDM screens being developed as option for remote monitoring
SUBSYSTEM UPDATES
MAGNET
- Work ongoing
FRAME (Carlos)
- Progress with the assembly - PMT blocks, mu metal assembly,
- Preshaping of wrapping - action: send material to JLab
MECHANICAL (Paulo)
- Req rails for detector out
- Platform already out
- Items left to do:
- magnet support and plate that goes under it
- patchpanel model - where it goes - how it looks like
- beamline - square section in front and a few small sections afterwards
- corrector magnet
RADIATION DETECTOR AND SETUP (Alexandre)
- Preparing tests with helium ionization chamber to measure neutron and photon separately
- Could the setup provide possible anode current measurement in Hall A/C?
TO DO LIST 2020 REVIEW
- Largely on track with schedule adjusted for Covid-19
- Roughly half of list for frame is done
- Crytals on schedule
- HV dividers - plan for path forward exists, waiting on lab resuming normal operations
- Analysis software development ongoing, e.g. see Jacob Murphy's presentation
- Much progress by DSG
- Action: Ask FE/DAQ for presentation at a future meeting
CPS POWER ABSORBER (Bogdan)
- Deformation risk for Cu core due to high temperature (~400-500 degC)
- Narrow beam channel and 40cm long piece with diameter of only few mm
- Deformation of inside slot (where beam is) could be an issue - need beam alignment up to 1mm
- Should look at the details and see how to include room for motion - system is very compact with W shielding
NEXT MEETING: THURSDAY 30 JULY AT 9:00AM (ET)
