RUN 46- started at 00:50

Horizontal beam position = 4.0 mm, vertical beam position = -5.0 mm.

Detectors are Left arm OUT = 36.64, right arm IN =  64.60 mm

Injection at ca. 6E7

Target density 6-7E9

00:51

Merger OK, Tape server OK

ADC data item statistics looks as before. OK

FEE temperatures look OK

System checks OK

Leakage current stable

Attachments 1-2

01:19

Attachments 3-4 waveforms. DSSD0 stats fine

01:33

DSSD0 stats fine

Attachments 5-6 spectra and xy, but I am not sure at which time these are cause I am stupid and apparently the AIDAsort code was not running....

01:56

Restarted the AIDAsort code and noted that stats in DSSD0 were bad again. Another shake. This time no change to the beam on my side.

2:43

All checks fine. Attachments 7-10 (also spectra)

4:01

Notice stats on DSSD0 went bad again. Attachment 11. Gave detector a shake.

Now all system checks OK (Attachements 12-14)

4:19

Just noticed target is oscillating a bit, hitting 1E10. I moved it further in X and Y. Seems to not go below 6E9 in any case.

NOTE: target was on at x=-19899 y=500.

5:17

Merger OK, Tape server OK

ADC data item statistics looks as before. OK

FEE temperatures look OK

System checks OK

Leakage current stable

Attachments 15-18 (also waves)

5:53

Notice stats on DSSD0 went bad again. Gave detector a shake.

6:10

Stats ok in attachment 19, but

Noticed DSSD3 has started to get only a fate of 140 nstead of previous 5500is (similar to what DSSD2 has done earlier- see previous elog). Attachment 20 for the rates.

I have therefore made the Check ASIC control test from the ASIC control tab- attachment 21 with results.

DSSD3 back to normal operations - attachment 22
