Pinned, e744, Wed May 23 17:23:34 2018, Freddy, MUST2, General, , Pedestals and alpha calibration analysis
|
Calibration coefficients for MUST2 telescopes were extracted from run_0118 (acquired during night from 13th to 14th of May). They are now located in the folder:
/home/e748/analysis/nptool/Projects/e744/Calibration/Energy/Calibration/Summary_run_0118
Based on the analysis of this run we realized that:
- T4_StripX had pedestal normalization issue (for MATE 1,3,5,7) and alpha peaks were enlarged or doubled.
- Pedestals used until today (23rd of May) were based on the pedestal measurement of the 28th of April !
Due to that, we remeasured the raw values of the pedestals today and compared them with the one used up to now.
The differences (in channels) between these two pedestal values for each telescope are plotted on the attached figure (X from 1-128 and Y after).
The drifts can be partially understood by the fact that the conditions evolved a lot during one month (cooling system temperature, etc).
For the online analysis, calibration of run_0118 (13/05) will be used but they somewhat lie in time between the two pedestal measurement (28/04 and 23/05).
However it is important right after the experiment to perform a new alpha calibration in conditions much closer to the measurement. |

run #430 exl ppt triggers. Changed val on gmtslave also
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). |

Configurations files of the MUVI 1 MufeeX and Y.
On MufeeX and Y configuration:
Note that the thresholds on Must2 T1 to T3 is at 400 keV on May 23th Midnight (same as before); and for T4, now it is set at 1 MeV (not 400 keV).
On Muvi/CAS configuration :

run 443
T1-T5 triggers
still problems to recover the counting on must2. Cats: 5000 pps , T5: 50 pps max
Below changes in tuning with little change in counting...
The energy for 14N7+ at the entrance of must2 should be 28.44 meV if the beam dump thickness is correct (34 um). If a dead layer of 0.5 um of Al is included, the energy became 27.849. This looks very close to what we see on X strip, and about 1 MeV off on Y strips. |

No stop on t5, but TAC MM_CATS ok.. So two possibilities:
1) Stop Cable not connected on Muvi2
2) Problem with the validation of CATS by FAG
HF validated by FAG was not working
Dead time scaler was not working
We need to erase all the scalers at the beginning of the run, including the part from Muvi (ORD, DESC, etc). Atm we erase only the U2M not the other part
The big problem is the transmission between LISE silicon detector D6 and T5 must with CATS on or off. 3000 counts/s on silicon d6 or CATS -> maximum 300 on T5. Is there a way to miss counting in Must2?
TAC_CATS_HF ok
TAC_MM_CATS ok
T_MM_EXLor present with prompt from cosmics?!
T_MM_HF ok
T_MM_HFv not present |

Nb: The applied threshold is now 1 MeV but it seems to be not the case when we look at the spectra.
Maybe a problem of the read configuration in GECO.
