Subject: Run 50/51 - data taking 

11:13

ML enabled ring signals remotely.

Used FakeMotion.dat (read FakeMotion.dat from InteractiveMotion.x).

Started run 50.

 

Cooler voltage moved up by 0.1 V. Did not refocus.

Setpoint = 244.4 V

Read = 243.85 V

Collector current = 4.3 mA

 

Target thickness 3.4E11 atoms/cm2 now stable

Injection 1-4E7 ions

 

Realised motors were not in.

Moved detectors in (36.54 / 64.60 mm)

Started run 51. Ignore run 50.

 

11:46

Realised the left half of DSSD BL was not counting. Checkloaded. Fixed it.

 

12:00

Fire alarm? Stopped later. EM thinks it is a test.

 

13:00

Run continues.

Rates OK. Merger OK. Writing to disk back to 200 kB/s. Nothing changed, reasons unclear.

FakeMotion.dat continues

System wide checks as before

Temperatures OK

 

13:36

Beam lost. Called HKR. Detectors out. Run continues. FakeMotion stopped

14:09

Beam is back. Detectors back in. FakeMotion.dat restarted.

 

15.10 High rates observed aida01-auida04 ( c. 250k/FEE64)

          Cycled Left Servo

         Rates normal
