Wastewater Experiment Commissioning Plan

'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. 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.
3. Open and close each valve and makes sure it hits its limit switch on both sides. Leave all valves opened when completed. File PR if problem arises.
4. Turn on gun to operating voltage.
5. Insert ITVK201
6. 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.
7. Continue to set up keV beam to FC#1 per normal operating procedure.
8. Execute UITFList #### with Scott Windham and Weiwei Lu to map the Chopper Slit Encoder (Encoder motor was changed over the down)
9. Once mapped, withdraw the chopper slit (it will not be used for this experiment)
10. Continue beam setup to FC#2 per procedure
11. Establish beam to the keV spectrometer
    • 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
