'Gun Test Stand Mode:

  1. HV commissioning and processing of the gun
  2. Determination of Operating Voltage for a low FE or FE free regime

keV mode: (VBVM101 locked in)

  1. Insert Faraday cups 1 & 2.
  2. Verify manual valves VMVK203 and VMVK401 are open; open them if they are closed and vacuum is reasonable on both sides of the valve.
  3. Using the laser amplifier, configure it to create a low current CW beam of ~10nA
  4. Systematically insert all of the Viewers in the keV region. Verify they all insert, retract, and are focused and the the lights work. File PR if problem arises.
  5. Open and close each valve in the keV region and makes sure it hits its limit switch on both sides. Leave all valves opened when completed. File PR if problem arises.
  6. Verify all vacuum pumps in the keV region are on and at reasonable voltages/currents. File PR if problem arises.
  7. Turn on gun to operating voltage.
  8. Insert ITVK201
  9. MBHK101H & V, MBHK102H & V, and MFHK101 were all disconnected this down
    • Verify the MBHK101H & V correctors kick in the appropriate dimension and with the appropriate sign. File PR if problem arises.
    • Verify the MBHK102H & V correctors kick in the appropriate dimension and with the appropriate sign. File PR if problem arises.
    • Use MFHK101 to determine the magnetic field which approximately focus beam on the viewer; use correctors as necessary to keep beam on the viewer.
    • Using the ditherer, dither the solenoid by 10% and use the K101 corrector pair to center beam in the solenoid (i.e. where there is no horizontal/vertical displacement as the field changes)
    • Use the K102 corrector pair to center beam on the viewer.
  10. Continue to set up keV beam to FC#1 per normal operating procedure.
  11. Execute UITFList #### with Scott Windham and Weiwei Lu to map the Chopper Slit Encoder (Encoder motor was changed over the down)
  12. Once mapped, withdraw the chopper slit (it will not be used for this experiment)
  13. Continue beam setup to FC#2 per procedure
  14. Establish beam to the keV spectrometer
    • Configure the laser to be able to generate Tune mode beam.
    • Take a harp scan
    • Calculate the beam energy based on the field and check that this matches what the gun voltage reports
    • Perform an emittance measurement using the K501 wire scanner
    • Perform an emittance measurement using the K501 viewer
    • Calculate beam emittance and twiss parameters per procedure and match beam to MFQK403
  15. Configure ~10nA CW beam to ITVK501. Set MDIK402 to zero BdL. Stop beam. Did the BLM ILMM402 trip? If not, contact SSG for help with configuring the right voltage/trip point.
  16. Is beam visible on the BPMs with 100nA of CW current to FC2? If not, file a PR on the relevant BPMs.
  17. Cycle all the keV correctors, solenoids, and diples and verify the beam setup is reproducible.
  18. Take an all-save if you haven't already. Record your progress in the logbook.
  19. When all exercises have been completed to FC2 (and with facility manager permission), take an access and remove the configuration locks from VBVM101 and the booster RF zone.

MeV mode:

  1. Ensure FC3 and FC4 are inserted
  2. Insert Faraday cups 1 & 2.
  3. Systematically insert all of the Viewers in the MeV region. Verify they all insert, retract, and are focused and the the lights work. File PR if problem arises.
  4. Open and close each valve in the MeV region and makes sure it hits its limit switch on both sides. Leave all valves opened when completed. File PR if problem arises.
  5. Verify manual valves VMVM301 and VMVM401 are open; open them if they are closed and vacuum is reasonable on both sides of the valve.
  6. Verify all vacuum pumps in the keV region are on and at reasonable voltages/currents. File PR if problem arises.
  7. Turn on the booster at the desired operating gradients for each cavity.
  8. Establish 10nA CW beam to FC3 per procedure.
  9. Insert IYGM501 (YAG) and establish beam. The viewer was moved and reinstalled this down. Camera alignment must be verified. The screen inserts from the Y+ direction.
  10. Using MHBK403H/V make horizontal and vertical kicks while observing beam on IYGM501. Does the camera behave as expected? If no - file a PR.
  11. The MLHM401H & V correctors were disconnected & repositioned this down. Verify on the YAG the MLHM401H & V correctors kick in the appropriate dimension and with the appropriate sign. File PR if problem arises.

  1. BLM Testing
  2. BPM Testing
  3. BCM Testing
