we reset the DAQ and did the module_restart with the card IP 192.168.3.78
no change

Iolanda | Problems | | Software | time alignement issue |
I have noticed that for run 56 there was the following message :
==> Checking modules synchronisation ...
Maximum time diffence is : 280.0
Does it mean a miss-alignement between the cards ? |

KWL GC | Problems | | Other | swap between 62Ni and 58Ni beam for run 6 and 7 |
Attached is the particle-gated gamma-ray spectrum for run 5 (green), run 6 (blue), run7 (red).
In run 5 we see clearly transition of 2+1 --> 0+1 in 62Ni, while in run 6 both transitions are visible from 58Ni and 62Ni (which is a result of a wrong beam tunning in to increase the intensity during which the ion changed by mistake). Now we are running with 58Ni (run 7) and waiting for Hakim to come to bring back the correct beam.
For run 6 the hour of data taking should be ok i.e. with 62Ni beam.

We observed a decrease in the particle energies. We attached one channel comparing with the same but from run 5. We keep running.

All | Other | | Other | change the foils every ~2 hours |
PAY attention to the stripper foil.
If the beam intensity drops to 15 enA, check the stripper foil.
It should be ~5 enA after the target (the meter on the counter) |

KHK, KWL | Problems | | Other | contamination in the chamber |
We see the the background lines coming probably from some activation inside the chamber as the target wheel is removed and we run only with the alpha source at the moment.
The spectrum is the same means that something inside the chamber is activated, not the target 197Au used in the coulex run or neither it's coming from the previously used target of 208Pb |
