DAQ

How to run

  1. Connect to the DAQ computer (you must use the LNGS cable network or the LNGS VPN:
    ssh my_user_name@172.17.4.212
  2. Load the DAQ software:
    $ source /software/LoadGAGG-DAQ.sh
  3. Prepare a TOML config file following the examples in the /software/config folder
  4. Run with:
    $ /software/GAGG-DAQ-build/bin/GAGG-DAQ /software/config/my_config_file.toml
  5. To make a loop of subsequent runs, open a screen session and run something like: for( ( i=0;i<1000;i++)); do /software/GAGG-DAQ-build/bin/GAGG-DAQ /software/config-files/Thermal.toml; done

How to install the CAEN libraries

  1. Create an account on the CAEN website
  2. Download the USB driver for linux for the V3718 bridge and install it as a system-wide installation. Notice: the driver talks to the linux kernel, so you will probably have to recompile it after an OS update.
  3. Download and install the CAENVMElib library (in C)
  4. Download and install the V65xxController library
  5. Download and install the GECO2020 software (for now we're using this to control the HV)
  6. Download and install the CAENComm library
  7. Download and install the CAENDigitizer library

How to obtain and install the DAQ software

  1. Send your github.com username to Giovanni (create one if you don't), then accept the invitation you will get via email.
  2. Clone the repository in a directory of your choice:
    $ git@github.com:GSSI-BolometerGroup/GAGG-DAQ.git
  3. Install the following prerequisites and make sure they're correctly loaded: CAENVME library, CAENComm library, CAENDigitizer library, ROOT.
  4. Create and enter a new folder for building the software:
    $ cd /path_to/
    $ mkdir GAGG-DAQ-build
    $ cd GAGG-DAQ-build
  5. Compile with cmake:
    $ cmake /path_to/GAGG-DAQ
    $ make
  6. You will find the executable under /path_to/GAGG-DAQ-build/bin/GAGG-DAQ
