How to take HARP scan

After first initial tune, we want at least one HARP scan on 1HA05A to determine absolute beam position after chicane change.

• Request 8 uA tune beam
• In Monticello, go in first HARP menu, select HARP expert controls and open panels for 1H05A and 1H04 ( bottom right of expert screen )

• Make sure speed is set to 1

• In Monticello, go in second HARP menu ( ! ) choose HARP analyzer

• Select the Hall A harp to use
• Click on Initiate scan
• If signals saturates, reduce gain on the corresponding HARP and take another scan
• If you see 3 distinct peaks the HARP scan is good, take another one if beam tripped during the HARP scan
