UITF pre-run0 commissioning steps (1/23/2020):

Hot checkout with beam and admin steps associated with commissioning plan

  1. Finish sending 200 keV beam to both waist height dumps, identify all the components that don’t work and get them fixed
  2. Call RadCon and SSG and coordinate shielding and BLM calibration (step 6 of commissioning plan)

Buncher Commissioning

  1. Beam to 200 keV spectrometer, find the two zero crossing phases, find crest and calibrate energy gain versus buncher gradient
  2. Beam to MeV spectrometer, verify zero crossing (is this step of any real value?)
  3. Measure bunchlength with Brock cavity, versus buncher gradient, find minimum and then scale graient to set minimum at two-cell

Optic studies

  1. Harp scans, measure spot sizes and compare to Elegant predictions
  2. Measure beam emittance
  3. Dipole calibration? We know it’s 200 keV beam
  4. Measure energy spread

Yao cavity time of flight system

  1. Work with Rama to see if it works
