Looking at AGATA count rate, we have seen that the highest counting rate for 511 keV line is seen in the inner ring (0*A clusters).
The outer ring detectors (10B for example) counts 10 times less.

The new box has been tested together with the new CAEN SY4527 power supply. We connected a laptop with Linux to the power supply by means of an ethernet
cable and communicated with it by opening a browser (http://192.168.0.1, then username: admin and pwd: admin). To control the channels we open a terminal,
go to the folder where we saved the file ChannelsController.jar and run the command: java -jar ChannelsController.jar 192.168.0.1 admin admin

We analyzed the behaviour of the annular. We realized that the 4-peaks behaviour on X was already present last year but only on one sector, now it's on
two sectors. We noticed that there is a correlation between the malfunctioning sectors and the missing strips on Y. Last year there was only a missing
strip on Y, affecting only one sector on X; now 3 strips are missing on Y, affecting 2 sectors on X. We believe that the fact that the boundings are missing |

Fixed, TEST, Wed Mar 11 18:12:40 2020, Marlène & Franco, GRIT, Hardware, N/A, Update on Mugast
|
(Probably) final update of the status of the detector before the experiment:
- MG5 does not trigger on Y (no pulser, no alpha source). This can explain why in the last experiment we could not run the time calibration of its Y.

Fixed, TEST, Thu Mar 12 10:14:02 2020, Marlène & Franco, GRIT, Hardware, N/A, Debugging the cooling system
|
We realized that the increase of temperature of MG7 and MG9 during run 600 (alpha calibration) was due to the fact that a loop of the cooling system was
not working since the pipes were not properly connected. We re-connected them and switched on the low voltage without making the vacuum just to monitor
the evolution of the temperature.

Fixed, TEST, Thu Mar 12 14:47:59 2020, Marlène & Franco, GRIT, Hardware, N/A, Moving MG9 square to MUVI2
|
- Since we are not using MG6 anymore (card burnt), we replaced it with MG9 on slot 3 of MUVI2. MUVI4 is now unused. We changed the actions parameters accordingly.
- We cannot run the time calibration for MG9 because the pulser does not go through neither on X nor on Y. |

Fixed, e793s, Thu Mar 12 14:54:13 2020, Marlène & Franco, GRIT, General, 3-alpha, Run 0601 - alpha source calibration
|
We start the alpha source calibration run with pedestal suppression (except for MG7 and MG9) and cooling at 0 deg.
The HV for MUST2 are in attachment. It is not clear whether they will remain unchanged during the experiment since some currents are high. |
