Valerian | OTHER | General | 3-alpha | Update on the cooling system problem |
After waiting for 1-2 hours. I started the BT again on T5 no tripping BT anymore. While writing hardware with DAS T5 responded well.
After starting the HT, i started a new run :
run #206
start @18h02
stop @18h15
the spectrum seem OK.
In both cooling systems the levels are still good, did we refilled the 0 degree cooling system since the beginning?
The vacuum is @ 9.1e-6 in M2C and 2e-5 in 0 degree chamber.
I then left the cooling ON, but stopped both HT and BT on every telescopes.
I join with this entry screenshots of :
- T5 spectra
- BT&HT current before stopping
- DAS window for X&Y |

Valerian | OTHER | General | 60Co | Update on the cooling system and run gamma (signal problem on PPT) |
Today, both cooling system are working fine and their levels are OK.
The vacuum are 7e-6 mbar in M2C and 2e-5 in the 0 degree chamber.
I start a new gamma run :
run #207
trigger : EXL + PPT
start @10h44 07/05/18
stop @11h14 07/05/18
No signal on PPT. EXL OK.
I join to this entry a screenshot of EXL HT and EXL + PPT spectra
I start a new gamma run :
run #208
Bad run
run #209
trigger : EXL
start @11h21 07/05/18
stop @17h44 9/05/18 |

iulian | EXL-PPT | Hardware | N/A | Mesytech settings |
Tried unsuccessfully to change the gain on EXL energies.
Looking at the inspection lines noticed that all the EXL signals were inverted (negative) and we were coding only the pole zero part of the signals.
Looking into the manual find out how to change polarity of the signals. Did that and now the signals look normal with normal gain change after polarity change.
EXL polarity is negative so Mesytech modules have to be set to use negative input signals.

PPT HV = 650 V
This is happening when the pre-amplifiers for EXL are not alimented.. When they are alimented the EXL sigal polarity is positive.. The gains and thresholds for Mesytech modules are below |

François | DAQ | Software | | TDC problem |
Problem :
TDC labels are 0. After the compilation of action list the labels seem to appear (if I remember correctly), but after a save/reload of the config they are gone, and in all cases no event coded (on the oscilloscope a validation point is visible, but do not know what this means in the case of a TDC – even after looking in GANIL wiki related doc).
Solution :
Solved by Fred. He made "init" at the VME MUST2MASTER in the RCC. |

François | BEAM | General | | Profileur |
Normalement, les profileurs devraient voir le faisceau.
En général, la fenêtre d’entrée est de 12µm de titane et il y a une plaque d’alu de 3mm en sortie.
Donc il y a une plaque d’arrêt sur le dernier profileur.
Mais même si c’est une feuille d’inox en sortie, le faisceau ne devrait pas sortir.

TED4_HF (cable physically labeled 29 of the ADC)
