Valerian | MUST2 | General | 3-alpha | T5 : 0° telescope |
After increasing the voltage on T5 DSSD from 80V to 100V the resolution increased from ~40keV sigma to 20keV sigma.
StripX vs StripY bidim and the 3 alpha peaks are joined to this entry. |

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.

start @8h15m55s 12/05
stop @20h01 12/05
This run use new das config copied from e744_save04mai_fonctionne.das, updated and then re-saved to e744_save12mai_fonctionne.das
The previous config , saved now under the name e744_save12mai.das, gives no Y energies in the spectras and an error on Muvi2 (some register different) |

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.

The following TACs signals from LISE have been cabled and send to the experimental acquisition (->D6)
TED4_HF (cable physically labeled 29 of the ADC)
TE2D6_HF (cable physically labeled 30 of the ADC)
--> They should be added to the DAS when possible
NOTE that TE1D6_HF (cable physically labeled 31 of the ADC) was already cabled |

Calibration coefficients for the PPT detector using the 60Co and 40K lines: E=0.5514*ch - 83.322. Internal radioactivity at 1444 keV, not separated from 40K
Efficiency: During the run (21h46min40s) the number of gammas emitted from the 60Co source is 66796800; for the Co pics the integrals are: 2.71e05 for the 1173.2 and 1.87e05 for the 1333, respectively (0.4% and 0.3%) without geometrical factor |
