• Division is asking us to finalize all work travel requests through Sep 30...
  • May - IPAC'23 (Greg/Aziz/Joe) and LCWS (Andriy/Carlos)
  • Jun - Quantum Meeting (Riad)
  • Jul - ?
  • Aug - ?
  • Sep - ?

• Papers and proceedings...

(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

• Proposal status...

(pending) - SLAC/KEK/JLAB HEP - Supports ILC PES and e+ target (Carlos, Andriy)

(pending) - DOE ECA - PES with 1000x better vacuum (Mamun)

(due 6/23) - LDRD PEPPo-II (Max)

Jun'23 - CBE (Marcy)

Sep'23 - Comtra (Riad)

Sep'23 - HVINS (Carlos)

Sep'23 - Robust (Joe)

• GTS
  • High voltage insulator/plug tests ongoing
  • TE011 cavity...?
  • Eventually GTS could go to LERF

• CEBAF PES jobs...
  • 200 kV gun - bake out, laser alignment, HV conditioning, gun kick/spot move, picks bias voltage
  • 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 with I&C

• UITF rest of this year...
  • 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)

• Students (Sami, Sunil, Aziz, Greg, Kawser, Sohaib)
