This page is intended as a portal to information about the processing of the data taken during the summer of 2019.

Data Taking

Information about the run can be found on the HPS Run Wiki. A selection of runs deemed of production value has been generated and can be found here. This is the list of 295 runs described in Rafayel Paremuzyan's talk at the 2019 Fall Collaboration meeting.

Data Snapshots

During the run, individual partitions were cached on disk and processed to provide near-real-time data quality monitoring (DQM) plots.

Selected partitions (all files ending in 041 and 042, representing ~1.6TB of data in evio format) of selected "good" runs are now available on disk for pre-processing.

They can be found at JLab on /cache/hallb/hps/physrun2019/data/hps_*/*041 and /cache/hallb/hps/physrun2019/data/hps_*/*042.

They can be found at SLAC on /nfs/slac/g/hps_data2/data/physrun2019/samplePartitions/

Reconstruction Passes

A first pass reconstruction was performed using a snapshot of the master branch.

The latest version of the jar file can be downloaded from the nexus repository at https://srs.slac.stanford.edu/nexus/repository/lcsim-maven2-releases/org/hps/hps-distribution/5.0/hps-distribution-5.0-bin.jar

Events were reconstructed with the following command line:

java -Xmx896m -Xms512m -cp hps-distribution-5.0-bin.jar org.hps.evio.EvioToLcio -x /org/hps/steering/recon/PhysicsRun2019_pass0_recon.lcsim -r -d HPS_TY_iter4 -e 1000 -DoutputFile=outputFile inputFile

Events containing at least one reconstructed vertex were then skimmed. The output can be found at SLAC at /nfs/slac/g/hps_data2/data/physrun2019/samplePartitions/20210401/v0skim/  

Analyzing these files should provide a good idea of how conditions changed during the run.

Single evio files

The evio format of a certain set of runs have been stored on SLAC machines at 

/nfs/slac/g/hps_data2/data/physrun2019/

And a few have been reconstructed producing 

  • Reconstructed slcio files (Run 10031)
    - Processed with iss687, v2 detector, outputs stored here.
