 Sun Jun 16 07:08:10 2019, Ela, Sonja, Victor, Alejandro, problems in coincidence crystals-F11 
|
We have noticed that there is a problems in the coincidence Crystals-F11. The TAC shows a lot of counts. The
Crystals spectrum in coincidence with F11 do not. The time window of this coincidence is from-50 to 50 samples
and it should be from -180 to 300 samples to be centered in the peak of the TAC.

Mon May 27 13:50:54 2019, A. Algora, preparation directory moved
|
| The preparation directory was moved to /data/DRikenPreparation (from its first place /home/dacq/DRikenPreparation) because the lack of space. |

New config file: 20190606_Conf.xlsx
Changed with respect to the earlier file (20190605_Conf.xlsx):

Setup: On 17th-May (11:18 - 11:38), AIDA was inside DTAS. Measurement of 60Co source.

Tue May 21 06:44:18 2019, A. Algora, identified useful sources
|
This is a short list of the identified useful sources:
60Co, key 3, red box, CD 395, already used
137Cs, key 8, 4753, CS401, activity ???, already used |
|
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 |

Sat May 18 01:41:45 2019, 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.

Sun Jun 9 04:03:38 2019, Jorge, Jose, Pancho, Alvaro, Kike, Ale, effect of the pulser in the low energy part of the anodes
|
There is an effect if the pulser is at higher frequency in the low energy part of the anodes (apart from the funny situation that the scaler shows an
increase from 1.7 Khz to 8.5 kHz and the dynodes rate remain with the same rate)
The effect can be seen in the spectrum of the anodes. See screenshots in the attachment. First attachment (pulser at 10 Hz, second attachment |
|
Mon May 27 07:11:22 2019, A. Algora, detectors realigned with Cs
|
Small alignment corrections were needed, of the order of 0.5-1V.
All detectors were realigned |
|
Thu May 16 02:02:24 2019, Algora Kiss Nacher, detector 3 moved over night
|
After the long background measurement we have measured 60Co to check alignment.
Everything looks fine except for detector #3 that has moved to lower gain (seen in dynodes and anodes).
See figures attached. |
