The Gatconf parameter is now defined in the action file.
The new configuration for GMT (see chronogramme plot) is attached, with the FAG window width set at 100 ns. |

Pinned, e748, Thu Jun 15 10:16:03 2017, Valérie Lapoux, MUST2, Hardware, , Electronics for GMT trigger and FAG
|
The GMT is used in a mode where we do not make coincidence and decision, GMT entries are single and all accepted as triggers of the DAQ.
The FAG window for the GMT should be set at a low value, typically 100 ns. |

Pinned, e748, Thu Jul 6 02:41:13 2017, Freddy and the night shifters, CHIO, General, , CHIO analog treatment
|
Interestingly, the bipolar output of the amplifier of the CHIO sent (and splitted) to check correlation on the channel 15 of the ADC CHIO (or on channel 29 of the ADC MUST2) provides a much better resolution (about 10%) than the one obtained using the unipolar output that we were looking since then (about 20% resolution).
This can be understood by the fact that the bipolar signal from the spectroscopic amplifier filters the baseline fluctuation by deriving the unipolar signal.
On the attached PID plot, it is easy to see the improvment. On the other hand, the beam spot extends also at lower channels and covers part of the other lines.
Since the unipolar signal will have some negative part (undershoot), it is possible for pile-up signals to arrive on top of this negative part and end up with lower energy.
With numexo, the energies extracted from the digitized signals, this undershoot issue is not visible. |

| iulian wrote: | 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 |

Pinned, e744, Tue May 22 18:33:32 2018, Nicolas, Adrien, OTHER, Software, , How to run Online and Convert raw data files
|
1. How to run Basic_online or Online code
- From any computer (logged as e748 user), type 'online'. This logs you to the lpcgrit server and the online directory
- From the command line, run 'start_online' to start the Online code
From the command line, run 'start_basic_online' to start the Basic_online code
2. How to convert raw data files
- From any computer (logged as e748 user), type 'conversion'. This logs you to the lpcgrit server and the conversion directory
Now, two options are possible (first one is preferred)
- From the command line, run './run_convert.sh run_number'
This converts the raw data files which have not been converted yet since run_number
- From the command line, run './Convert run/run_file_to_convert rootdir/converted_run_name.root
This converts runs one by one

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. |

|
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 |
