Adrien Matta | MUST2 | Hardware | | MUST2 cabling scheme |
The MUST2 cabling scheme has been change so Telescope 1 to 4 and 5 to 8 are on two independent set of distribution box and HV Card.
Telescope 1 to 4 are on the small distribution box and the first HV card. This correspond to the down stream flange.
Telescope 5 to 8 are on the large distribution box and the second HV card. This correspond to the port side flange.
CAEN SY1527 setting has been changed accordingly. |

Adrien Matta | EXL | Hardware | | EXL ADC gate |
EXL ADC is now setup with individual gate on the ADC.
We also put the threshold higher to reduce the rate and managed to work on timing.
We still think we need to delay the trigger output from the Mesytec module so the GMT is not triggered too soon.
However its appears that the trigger arrive 40-60us before the signal. Not sure if the AI output of the ADC is working properly, need to check this with Fred.
After checking the signal on the scope out of the MSC16 everything is in time. |

Adrien Matta | ONLINE | Software | | Starting the GRU online analysis |
We setup a script to start the right environment to run GRU, ganil2root and nptool.
The script is located in /home/muvi/e748 and can be accessed by just typing online in the terminal.
This will start bash and source the relevant files.
Online and offline GRU script are located in the /home/muvi/e748/nptool/Projects/e748/online and /home/muvi/e748/nptool/Projects/e748/offline respectively.
The GUser class in both folder need to be compiled using the provide Makefile (so just do make after editing the GUser.cxx and GUser.h).
To start the GRU spectra server for online go to the online folder and type GRU Online.cxx
To convert a single file from .dat to .root go to the offline folder and type GRU Offline.cxx |

Adrien Matta | ONLINE | Software | | Online/Offline list of task |
We need to do the following improvement to the online / offline environment:
- Provide two separates script for starting Online and Offline environment, that goes directly to the right folder. : Done
- Make an Offline program instead of a script, so we can provide argument : Done bu Valerian and Adrien
- Make a bash script for automatic conversion of the runs : Done by Valerian

Adrien Matta | DAQ | General | N/A | DAQ issue summary |
Previously on e744:
After a chat with Charles Houarner we decided to have configuration with a Muvi card per VXI crate. This is supposed to reduce the dead time (DT) by parallelising the crate readout. This have a few implication:
- The slave crate need a GMT, because the MUVI read out was never tested using a GAMER
- The GMT is not designed to act as centrum receiver, so a centrum slave module is installed in the slave crate
- The action file compilation is not designed to have a centrum receiver, so the compilation has to be done by Fred. He is working on fixing the issue, in the mean time, we SHOULD NOT try to change ADC/QDC/TDC label and recompile throught DAS
- The slave GMT needs to be block correctly, Charles setup the VIS2/BLK signal with a logic FIFO.
- The slave GMT is triggered by the master GMT VAL
- The MUVI from the Slave VXI is still triggering the MASTER GMT, as usual.
After all this setup, we change the NARVAL topology to have two crate and a EBYEDAT merger. This merger prove to be no longer functional. Clotilde had a look but have no clue so far why it is not working.
We switch to MFM data format with a EBY2MFM merger. Because of this change of format we had to change both Online and Offline program in order to extract the EBYE buffer from the MFM frame.
This is no tested and working, for some reasons it worked only using ROOT6. |

Adrien | MECH | Hardware | N/A | Surveyor mesurement |
The surveyor are carrying out the measurement of the detectors in D6.
The measurement should take the day, starting with the main plate, and then in the afternoon the detectors.
All measurement done, WAITING FOR REPORT. |

Adrien | VACUUM | Hardware | | Vacuum Leaks |
We reach a stable 1e-5 mbar. We performed a leak check and identify that the Ionisation chamber gate valve is not totally tight, I don't think there is much to be done.
One of the M2C flange also have a micro leak, that we will solve next tuesday when reopening the chamber.
NOW FIXED |

Adrien | MECH | General | | MUST2 position |
After a the surveyor came we figured out the MUST2 telescope are 1cm too high with respect to the beam line.
Vincent is preparing new feet to replace the one supporting the main plate. We will support the plate with adjustable one while replacing the other so there is no need to dismount any detector.
NOW FIXED:
Vincent Morel and Laurent Meneger put in the new fit without unmounting the detector. all went smoothly. |
