FADC mode10 decoding update
- Julie, Pramita, Oliver and DJH had a meeting last week to discuss online software development.
- DJH 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.
- In order to do so, we can use data from a series of special mode10 runs taken during the recent PionLT experiment (listed at https://hallcweb.jlab.org/wiki/index.php/PionLT_2021_Physics_Status). The ten most recent runs (14024 - 14464) have been replayed and root files are available at: /work/halla/SBS/dhamilto/nps_mode10 (will move to /work/hallc/NPS/dhamilto/mode10 when I get the necessary permission).
- 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.
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
- cmake -DCMAKE_INSTALL_PREFIX=../ ../
- git clone https://github.com/JeffersonLab/hcana
- 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
- git clone https://github.com/JeffersonLab/hallc_replay_lt
- 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:
