We start a new run: beam is ok, target density ok, detectors are moving in-out periodically.

Cooler voltage setpoint  1105.7 V

Attachment 8 - beamcalc with actual values

Next entry - beamcalc with set values

Right arm at 19.80 mm

Left arm IN at 77.56 mm (OUT 32.53 mm)

vertical beam position 0.0 mm

horizontal beam position  -3.5mm

Beam intensity 1.7e+7 particles.

Target density ~6e11 at/cm2

Target temperatures: T1=31.5 K T2=35.2 K

Beam cycle set to 10 seconds.

All check are Ok!

6:30

Noticed a small spike in all leakage currents, see attachment 1

6:50

all checks ok!

07:40

All checks are Ok!

Aida 10 shows sometimes higher statistics.

09:02

All checks are Ok!

Aida 10 shows sometimes higher statistics.

10:00

Checks OK.

Compression works OK.

Moved to run 23. Now moving RIGHT hand side detectors instead of LEFT hand side.

Motion 37.96 mm -> 83.69 mm

Left arm stationary at 18.86 mm

Planning to change energy around lunch.

11:35

Parameters are OK! Tragte density dropped down a bit: ~6e11 at/cm2

12:35

Parameters are OK! Tragte density dropped down a bit: ~1e12 at/cm2

13:10

Starting beam energy change. Detectors OUT.
