MD Item | Procedure Link | Machine Time | Responsible Party | Requirements | Details |
---|---|---|---|---|---|
Test LI17/LI18 PAU functionality for S20 energy feedback improvements | 1 shift | Preferred beam to dump, requires EP01 micro | Attempt to recommission fast phase shifters (LI17 and LI18 PAU subboosters) previously used for EP01 energy feedback. Will need some crusty old crates revived and almost certainly a lot of sage SLC timing guru guidance. | ||
Collect SYAG data with variable compressions | 4 hours | Beam to dump | Data collection to interpret compression profile of SYAG with the goal of further calibrating that screen. | ||
Improved BC20 BLEN vs L2 chirp | 1 Shift | Beam to dump, more XTCAV juice | Recollect data for actual XTCAV bunch length over a chirp scan now that we have more streaking. Possibility for a 2 dimensional scan by repeating with variable L1 compression. Suggested to not recalibrate XTCAV during scans. | ||
Injector LLRF firmware updates | 1-3 days (passive) | TID readiness | Upgrade the LLRF firmware for 10-2, 10-3, and 10-4 to match newer versions deployed at 10-5 and LCLS XTCAV. Should be fairly quick to implement, but preferred to have at least a few days to monitor to make sure it works as expected. | ||
Any outstanding RP surveys | 4 hours | Variable | Parts f (beam to heater screens) and maybe n (external surveys with beam to S20 collimators/notch) or others. | ||
2 nC stability tests | 1 shift | Beam to dump | Investigate emittance blow up at higher charge, see if this reproduces with single bunch now that we have consistently compressed beam at 1.6 nC. | ||
PLIC indexing | 10 minutes | Beam to dump | Generate losses in known locations to calibrate X xcale of PLIC (for known scope settings) in order to have a calibrated loss monitoring system. | ||
Software commissioning | 2-4h | Beam to dump |
