UITF Notes

MeV beam time

• Measure MeV dispersion with BPMs => Done, need to analyze
• TM beam to 703 to see RF drift (full shift)
• Verify optics setup for HKDL
• Repeat buncher study, booster crested, 8 MeV, multiple scans per point

keV beam time

• LVQE scan at different voltages. Expect same result, provided different laser powers at same voltage give same result (avoid SCL).
  • Results are different, don't know if related to instrumentation (battery resistance etc.) or physics. If it's physics:
    • CST: Does thermal energy affect collection efficiency?
    • Ion current? probably too low to matter
    • Try adjustable bias voltage source (Keithley)
• HVQE scan at different voltages. Expect different result.
• High current to FC2 for 12+ hours, check if drift is gone
• Look at mains-harmonic BPM signals as a function of parameters (buncher etc.)

Beam line modifications

• Put HKDL stuff into the machine ahead of time!
• Fix miswired MeV correctors
