|
There is an issue with the GMT slave. When you click Online and then apply write hardware, if the message : register error on GMTSlave appear, reload a functioning DAS config and do not write hardware twice.
If you use write hardware twice, the error will disappear, but almost no triggering of the GMT will occur. |

turbo pumps stopped at 8H45
problem with the cooling system of the M2C chamber, the liquid was in the pipe but it was stopped, no flow, with a lot of "dusts" (vert de gris) => decision = we purge the pipes and the cooling system, once again ! |

start @11h15 05/05

Cooling stopped on T5, the cooling system was beeping with a LLL error, I started it again but it stopped with this error again... I stopped the BT and HT on T5.
One of the BT was tripping. I looked at the DAS, but the temperature seemed Ok... but I have no idea if they reflect well the reality...
I join to this entry screenshots :
- the CAEN 1527 terminal
- the das of MUVI2 channel 1 X&Y
- the vigru screen updated
- The LLL error
After calling Francois and Laurent Menager, I refilled it with alcool from the blue containers. It seemed to be working again. |

|
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 |

After struggling with the noise, we achieved ~ 50 keV resolution.
Source = 1 alpha peak 241Am E=5.485 MeV
Detector E1D6 50 µm 25 V in principle, but set to 100 V
Detector E2D6 300 µm 70 V in principle, but set to 100 V
PA gain = 20 mV/MeV
Maximum output signal of the new PA (differential) = 8 V. |

The correlation between MUST and PPT (run430_E_PPT_vs_T_PPT.pdf) is due to the beta decay of 138La (internal contamination in the LaBr crystal). PPT detects the beta energy with 100% eff, while the gamma rays - emitted in the beta decay process- interacted in MUST detectors. The EXL bidim shows only random events (no internal contamination). |
