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. |

A. Algora | background |
Start: 16:25
Stop: 17:25
Background in the same conditions as before (right after the Co measurement)
Listmode: Background_201905201614_035.dlt .... Background_201905201614_036.dlt
Root file: 201905201725_background.root
Rates:
Dynodes: 8.5 kHz
Anodes: 1.8 kHz
Anod1: 120 Hz
Anod15: 173 Hz
Dynod1: 80 Hz
Dynod 15: 166 Hz
Pulser set to 10 Hz
Rate of Dynode 5, 15, 17 seem a little higher than the others. The same for Anode 11, 15, 17
Not clear why the Dynodes rate is so high compared with the anodes. There is not such a big
difference in rate of the individual detectors.
(Dynodes and Anodes rates are taken from the Python script written by Jorge, that correspond to the full card)
Later it become evident that probably we need to increase the threshold of detector 8 again (Dy08).
Before it was not like that, but now seems to be triggering in the noise.

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.
Rates per detector of the order of 1.7 kHz, Ref det rate 63 Hz, with the pulser set to 10 Hz
Now a check on the other available sources will be performed.
Until now the used Co source was CO401(2530) , which is rather strong (corresponds to key 6)
and the Cs source was CS401 (4763) (key 8). This Cs is fine.
Now the sources on the red box (color ?) will be explored.

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
Root file: 201905201404_137Cs60Co_calib.root
Rates; 53 kHz (Dynodes), 47 kHz (anodes) So thresholds should be checked
Anode 12 (calibrated) has a large jump, because the cable in the digitizer was not fully plugged.
We need to recalibrate them. The alignment was done originally with Dynodes. |

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.
It looks that the calibration might be sligthly shifted for detectors 12, 13,17 (Dynodes) |

Nacher, Algora | gain check after the night |
Only PM3 showed an small jump. It seems that it has moved. Even after changing the HV cable. We will pay attention to it in the next days.
The others seem stable.

Det 3 moved, both Anode and Dynode. So we have changed the HV cable to test if there are no more jumps. We used cable 9 and it was not
relabeled. The HV of the detector was corrected. It was changed to 527.5 V |

Algora, Kiss, Nacher | DTAS aligned and calibrated |
Signal cables (long cables, from preamp to digitizer) of channels 13 and 16 were changed. For the moment they have not been relabelled.
We assumed that it was not a HV supply or cable problem, since the anods were aligned and only the dynodes moved.
After changing the cables we realigned the dynodes and recalibrated all signals. Screen shots are attached.
File (root file) with the two sources (Co and Cs) saved as 201905151432_137Cs60Co.root
Configuration file: 20190515_Conf.xlsx
