Old Topics
- Sami - evaluate e+ yield and final momentum as a function of capture linac parameters (gradient phase aperture)File:QWT 3.pdf
- 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
