UITF Notes

MeV beam time

• Measure MeV dispersion with BPMs
• TM beam to 703 to see RF drift (full shift)
• Verify optics setup for HKDL
• Ascertain the true frequency of the aliased GMES peak. Can the 105 kHz peak be the same that was 692 Hz in the last run?
• Buncher scan at 2-cell=2.5, 7-cell=9.0, both crested
  • 6.2: IHAM703.07242022_15:16:35 0.6895

keV beam time

• LVQE scan at different voltages. Expect same result.
• HVQE scan at different voltages. Expect different result.
  • CST: Does thermal energy affect collection efficiency?
• High current to FC2 for 12+ hours, check if drift is gone

Beam line modifications

• Put HKDL stuff into the machine ahead of time!
