Mon May 20 03:18:03 2019, A. Algora, Co and Cs after two days
|
We have been running with Co and Cs for the weekend to check the overall stability.
Seems that the detectors did not move too much. Please note that the Ref detector was plugged incorrectly in channel 8
instead of channel 10 of the ancilliary card. A new run will be done to include the reference detector. |

Mon May 20 06:04:41 2019, A. Algora, Co and Cs short file
|
Short file with the strong Co source and Cs source. To test stability
Start:11:32
Stop: 14:04 |
|
Mon May 20 06:31:53 2019, A. Algora, gain correction
|
Only a very small correction was needed (at the level of 0.5 V) for the raw spectra of det 6,12,13,17 (raw Dynodes)
New voltages
DET01 │ 599.0 V 1500.0 uA 598.5 V 89.5 uA On |
|
Mon May 20 06:55:15 2019, A. Algora, New config file after calibration
|
A file with Co and Cs was collected for 10 min
201905201444_137Cs60Co_align.root
after a minimal correction of the voltages (mentioned in the earlier entry). After this a new calibration was performed. |

|
Mon May 20 09:39:23 2019, A. Algora, Dynode 08 threshold changed
|
Dynode 08 threshold was changed from 675 to 790. Now the rate in this detector is fine.
The global rates for the cards (dynodes and anodes) are similar. |
