Apr 4, 2023 - CIS Group Meeting

Stream of consciousness agenda...

Property - validations are now due April 30th
Safety - everyone's doing pretty good, thanks - keep it up
Vacations - are on the horizon - please share to my Calendar (as free)
Lab vehicles - you can reserve for work - see Lynsie Tedrow - https://www.jlab.org/facilities/vehicles
Sharepoint - you have access to share (backup) files with one another - CIS Sharepoint (internal)
Lab IP - you can share your documented work, use Jlab funding statement - https://www.jlab.org/info_resources/publications/notice

(Joe) Polarized Beam Dynamics and Instrumentation in Particle Accelerators (USPAS Summer 2021 Spin Class Lectures)
(Gabriel) PSTP Penning cell Wien filter
(Josh) Charge lifetime improvement of biased CEBAF photogun
(Greg) A Compton polarimeter for SRF photoinjectors
(Max) Upgraded Injector Test Facility
(Joe) Positron white paper
(Riad) Electron EDM
(Riad) Quantum computing

Particle Accelerator Spin-Transparent Storage Rings for Beyond State of the Art Science
Making Extreme High Vacuum (XHV) commonplace in accelerators
A new polarized electron injector at CEBAF for parity violation
PEPPo II : a GeV positron beam experiment at CEBAF

200 kV gun - bake out, laser alignment, HV conditioning, gun kick/spot move, picks bias voltage
Fix photocathode activation Keithley 485 Picoammeter - bad display
200 kV Wien - 20 Amp PS, E/B spin calibration, benchmark model
Viewer/Harp/Kicker - fix short, add chopper valve/bake region, add new kicker magnet
Hall A laser jobs - remove ML, install repaired 250/499 board
KL jobs - install new amplifier for KL, test 499/32 setup, measure D pulse length, and laser size
Moller jobs - install IA in Hall D path, measure IA rise time, review RTP setup and laser table electrical isolation with I&C

Now operates like GTS with an OSP, Jessica safety warden and Joe POC
Focus will shift to using UITF to test photocathode lifetime/polarization (Greg, Aziz)
