Optimised motor motion during run R58

Moved 2 mm in (20.3 potentiometer)

29.47 potentiometer

36.5 potentiometer

(started moving pneumatic)

64.36 potentiometer

74.03 potentiomater (servo in by 10 mm)

Moved in, collected counts for 5 minutes, moved out, waited for re-injection.

20.3 - 400 counts on the Rutherford peak, bins 125-131 on lowEnergyExTotalDSSD0

20.47 - 646

36.5 - 827

64.36 - 3900

74.03 - 10040

Based on Rutherford rate ratio, estimated we are 40-50 mm away from interaction point, i.e. beam roughly 1-2 cm on outer half of ring which may be consistent with BPM measurement in YR08

Decided to use 74.03 mm for data collection.

Started data acquisition on R59 at 17:27

Beam 3E7 at injection, 600 second storage, 3 second between cycles

Target pressure 1.3E12 based on 8.21E18 x S1=1.6E-8
