New run 52 with:

Electron cooler setpoint 244.2 V

Electron cooler read 243.66 V

Collector current 4.3 uA

Right arm at 64.60 mm

Left arm IN at 36.54 mm

Target 2E11 fluctuating

Injection ca. 5E7

22;00

Detectors moved out while HKR plays with the beam injection to improve its stability

22;56

All system checks good. Detectors still out. Stats in attachment 1

23:08

HKR still has to call, but I have put detectors back in since they are only operating on injection.

Noticed that from time to time the target density still sparks to E12, and this corresponds to when the temperature drops.

23:42

HKR called back, they found the problem and fixed it. Beam seems more stable, with injections at ca. 5E7

23:50

DSSD0 high stats, cycled the motors to clear them.

00:18

All system checks are fine. Attachment 2-3 with stats and a spectrum

00:38

Spikes in the target got more frequent. Increased temperature to 30.5K and monitor if it helps stabilizing it.

01:52

All checks OK. Target behaving, density 5-8E11.

Attachments 4-5

03:10

System checks OK.

Target consistent

Some beam outages which were quickly fixed by HKR

05:03

System checks OK.

Target consistent

07:00

Lost beam. Detectors moved out

Will likely end run once beam is back and change energy. Do not use data past 7 am

All system checks OK
