We start a new run with real data taking condititon: beam is ok, target density is 5e11 cm-2, detectors are moving in-out periodically.

Cooler voltage setpoint 1128.55 V.

Beam energy = 1.99 MeV/u (from HKR)

Attachment 1 - beamcalc with set values

Attachment 7 - beamcalc with actual values

Left arm at 18.86 mm

Right  arm IN at 83.69 mm (OUT 37.56 mm)

vertical beam position 0.0 mm

horizontal beam position  -3.5mm

Beam intensity ~2e+7 particles.
