CF put because AGATA went crazy.
The beam profile is shifted in comparison to the initial profile at midnight. The beam is touching somewhere.
We asked the beam operators to try to center the beam.

550V.
8:25 Faraday out
Fixede786s Fri Jun 28 08:57:21 2019 FreddyCATSGeneralCryo-3HeCATS scaler not compatible with beam rate
The CATS scaler si now around 100-120 kHz while the beam rate is still 40 kHz.

I checked the CATS signal and there is clearly noise who induce double logic signals. Not all of them are validated by FAG.

We should raise the threshold- call sebastien

9h32 : Stop beam to enter and raise the threshold.

CATS high voltage lowered by 20V from 580V to 560V (on request of J. Pancin)
Fixede744s Thu Apr 11 19:47:15 2019 MarlèneOFFLINEGeneral CATS charges in RUN76 and RUN77
Offline analysis to reconstruct the charges in X and Y for CATS.
The charges are lower in RUN77 because bias was reduced to 580V.
Wires seem to be all OK.
Fixede793s Thu Mar 11 04:34:58 2021 ablaihan, louisCATSHardwareCD2CATS and VAMOS tripped
at 4h15 CATS and VAMOS tripped probably due to too high beam intensity (~1.2x10^6 pps). We switched them on again at 4h30. All the 6 CATS in Board2 in HV by 525 V instead of 530 V.

We did not stop the run to not risk to crash the RCC. Events btw 4h15 and 4h30 will therefore have no time.
Fixede744s Thu Apr 11 09:05:37 2019 mugastCATSGeneralN/ACATS HV changed to 580
CATS HV changed from 600V to 580V.
Fixede744s Tue Apr 16 11:40:04 2019 mugastCATSHardwareN/ACATS HV
CATS2 HV was decreased to 540 V at 11h30 to avoid the overcurrent.

Need to monitor Efficiency, Time resolution as soon as the run restart with new target.
Fixede786s Mon Jun 24 03:08:49 2019 MarlèneRUNGeneralCryo-3HeBrho issue
We observe a change in the Brho of VAMOS : the charged states are divided in 2 !!!

Édit: it is now understood as ice water cracking on the upstream of the target.
