New Topics

  • e+ source transmission with 7cm and 3.5cm apertures
  • updates from the gang
  • what we want to do in FY23

Old Topics

  • Sami - evaluate e+ yield and final momentum as a function of capture linac parameters (gradient phase aperture) File:QWT 08 31 – Copie – Copie.pptx
  • Yves - begin working on injection/extraction lines from linacs
  • Dennis - update LERF to SL transport line to agree better with the FML costing geometry
  • Alicia - solicited for emission parameters for GPT, building model of Gun through QCM (desired matchpoint)
  • Carlos - evaluate gun voltage and electrode gap for 60 deg and E profiles vs. gap (compared to as built magnetic profile)
  • S&A will plan to measure LERF relative to CEBAF and cryo points for Joe, Kelly will add FML layout to CEBAF and provide Joe Gubeli points for CEBAF
  • Joe Gubeli - would like elegant lines when available, can show them in LERF model
  • Joe/Fanglei/Amy - exchange ideas/options for e+ spin rotator inside LERF
  • Joe - prototype experiment planning media:220831_LERF_injectors.pptx
