Agenda

  • DAQ and firmware
  • Slow controls
  • Decoding software (FADC mode10, VTP data, unblocking)
  • Online software (raw displays, gui, interface with ET system)
  • Offline reconstruction (clustering algorithm, multi-threading)
  • Other business

FADC mode10 decoding update

  • Julie, Pramita, Oliver and DJH had a meeting last week to discuss online software development.
  • We implemented the changes needed for mode10 decoding to the THcShowerArray and THcShowerPlane classes in hcana (firmware_update branch). This means we can now use the SHMS pre-shower and shower calorimeters as prototypes for histogram / display / gui development.

  • The files are called:
shms_coin_replay_production_14XXX_-1.root (run 14557 has the most events, around 130k)
  • You can find the corresponding variables in the T tree: eg the waveform branch for the SHMS shower is called P.cal.fly.SampWaveform, while the variables derived from the waveforms are called P.cal.fly.adcSampPulseAmp, adcSampPulseInt, adcSampPulseTime or adcSampPed.
  • Very quick and basic example scripts for waveform display:

Instructions for replay set up

  • If you prefer to set up the full replay chain, brief instructions are given below:
git clone https://github.com/JeffersonLab/hcana
cd hcana
git submodule init
git submodule update
git checkout firmware_update
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=../ ../ (or cmake3 on some systems)
  • You'll then need to add an $HCANA environment variable and add $HCANA/bin to $PATH and $HCANA/lib64 to $LD_LIBRARY_PATH
git clone https://github.com/JeffersonLab/hallc_replay_lt
cd hallc_replay_lt
git submodule init
git submodule update
  • Editing and calling SymLinkSetup.sh should help you set up the necessary symbolic links.
  • Quite a few of the mode10 runs are already on the cache disks at:
/cache/mss/hallc/c-pionlt/raw
  • Run a replay:
set the DB_DIR environment variable to ./DBASE (eg source setup.sh)
add the following lines to PARAM/SHMS/CAL/pcal_cuts.param:
pcal_arr_OutputSampWaveform = 1
pcal_arr_UseSampWaveform = 1
pcal_OutputSampWaveform = 1
pcal_UseSampWaveform = 1
and this line to DEF-files/PRODUCTION/50k/Full_Replay_50k_SHMS.def:
block P.cal.*
do the replay:
