Run 45 + end of late shift |
|
|
22:54
We have moved the gas jet target out (y=4000), the density has dropped to zero.
Started a new run (Run45) for background measurement.
Informed HKR that the experiment will be monitored remotely without on-site personnel. They will check on the beam intensity.
02:08
System wide checks OK
Temperatures OK
Leakage current going up - OK
Stats OK
Merger continues OK
Reset the online spectra (had not been done yet for this run).
20s rate looks fine, around 1000 counts/s on top left detector. Maybe we are hitting it with beam? But then we should be see a reduction in beam intensity, we do not.
04:00
System wide checks OK
Temps OK
Stats OK
Merger OK
06:20
Beam intensity quite unstable, but HKR is correcting - attach 7
Systems wide checks OK
Temps OK
Merger OK
Stats OK
Some interesting features can be seen in the online histograms, e.g. no peak at 16 MeV and a clear straight line in the Ex vs x plot.
07:20
DAQ crashed due to multiple merger / tape server / HTTPD server instances being opened on workspace 5
Cannot soft reboot. FEEs off. |
