Set up harp scan

1. Ask MCC to stop beam delivery in preparation for harp scans and to turn off tagger quadrupole (MQPAD00)
2. Remove all radiators
3. Move collimator to blocking position

Perform accelerator harp scans (quad off)

1. Ask MCC for three harp scans: 5C11, 5C11B, and tagger dump (AD00)
   • Remind MCC that all three should be done with tune beam

Perform radiator harp scan (quad off)

1. Ask for 100 nA CW beam
2. Perform radiator harp scan as described in this wiki page

Perform accelerator harp scans (quad on)

1. Ask MCC to turn tagger quadrupole (MQPAD00) back on with current of -4.2A
2. Ask MCC for three harp scans: 5C11, 5C11B, and tagger dump (AD00)
   • Remind MCC that all three should be done with tune beam

Perform radiator harp scan (quad on)

1. Ask for 100 nA CW beam
2. Perform radiator harp scan as described in this wiki page

Restore Production conditions

1. Ask MCC to take beam away and mask FSD for radiator movement
2. Insert
3. Move collimator to 5.0 mm diameter hole (can be done in parallel with previous step)
4. Ask for the appropriate current CW beam to be restored
5. Refer to this wiki page for standard production conditions
