AIPINJ Booster Install Kickoff injector upgrade related things: wiki.jlab.org/ciswiki/index.php/CEBAF_Injector_Upgrade
BIG PICTURE The gun voltage is increased to 200kV. The SRF Booster replaces the combination of Capture + SRF QCM. The prebuncher, chopper and buncher cavities remain, but now act on 200 keV beam (not 130 keV beam). CEBAF QCM output energy is optimized for 6.3 MeV; Booster output energy being tested @ UITF, may be closer to 7-9 MeV. 500 keV 130 keV Capture leaves QCM leaves Chopper Prebuncher Chopper Buncher Booster arrives 200 keV
Items in red boxes remain as-ispretty much everything else is reworked or replaced. Chopping Solenoids/ LLRF Wien Filters/ Solenoids/ PSS Kicker Buncher/ Capture/ Spectrometer Cryo/SRF Polarized Source Cryo lines Cryo lines Chopper Chopper

Booster Installed at UITF Installation (handling, egress, vacuum, clean-rooms, alignment, interfaces) Cryo (u-tube, plumbing, controls, screens, software) High Power RF (HV, klystrons, controllers, waveguide, cables, screens, software) LLRF (digital RFCM, tuners, cables, screens, software) I&C (vacuum, interlocks, controls, cables, screens, software) Coordination (scope of work, labor, procurements/fabrication, schedule) Safety (different groups, electrical jobs, cryogenics, high power, unique stuff)
