The configuration and interaction with the Nevis electronics are done through the following utils:

The low-level commands are documented here:

SBN-ND reception tests

To test at DAB: ssh to sbn-daq01.fnal.gov (first ssh into one of the sbndgpvm*.fnal.gov or connect with Fermilab VPN)
To test at SBN-ND: ssh to sbnd-gateway01.fnal.gov, then to the TPC server (Crate) you want to test sbnd-tpc{01 .. 11}.fnal.gov (first ssh into one of the sbndgpvm*.fnal.gov)

There is a Bash script at\

/home/nfs/jcrespo/run.sh

to run the Nevis electronics. It gives you 8 run options (6 at DAB):

        (1) WIB data: 2-stream with External triggers _(→ Requires to run Crate01 – Trigger Board –)_
        (2) WIB data: 2-stream with Internal triggers (1 Hz) _(→ Requires to run Crate01 – Trigger Board –)_
        (3) WIB data: 2-stream with Controller triggers (1 Hz)
        (4) Nevis fake data: 2-stream with external triggers _(→ Requires to run Crate01 – Trigger Board –)_
        (5) Nevis fake data: 2-stream with internal triggers (1 Hz) _(→ Requires to run Crate01 – Trigger Board –)_
        (6) Nevis fake data: 2-stream with controller triggers (1 Hz)
        (7) WIB data: NU-stream with External triggers _(currently available just at SBN-ND)_
        (8) WIB data: NU-stream with Internal triggers _(currently available just at SBN-ND)_

The modes with Controller triigers do not show information in the XMIT Counter Info Report so the progress of the run cannot be monitored in real time.

The Nevis fake data takes ~ 30 seconds/FEM to configure, which increases significantly the configuration time.

Default Nevis fake data is “channel” number. Edit the fcl file called in the run.sh script to change between the predefined fake data modes.

The run.sh script creates a directory with the DAQ log, the art-root file from the NU stream and binary dumps of the NU and SN streams.

The decoder and analyzers at:
https://github.com/NevisSBND/DecoderTools/tree/master
can be run on the binary dumps to check the data quality.

The raw binary data format is described at:
https://sbn-docdb.fnal.gov/cgi-bin/private/ShowDocument?docid=17726

DAQ Digitization (conversion to LArSoft raw::RawDigit)

An area has been set up to run digitization on the artROOT fragments from the DAQ (thanks, Gray Putnam!). To setup the area:\

source /home/nfs/gputnam/sbndqm/setup.sh

then to digitize a file, run:\

lar -c daq_digits.fcl -s /path/to/fragments.root -o /path/to/output/digits.root

This will generate an artROOT file with the raw::RawDigit data product (one for every input channel).

To take a look at the waveforms:\

cd /home/nfs/gputnam/sbndqm/srcs/sbndqm/sbndqm/dqmAnalysis/TPC/fcl
lar -c daq_digits.fcl -s /path/to/fragments.root -o /path/to/output/digits.root
lar -c analysis.fcl -s /path/to/digits.root -T /path/to/output/analyze.root
python waveform_plots.py /path/to/analyze.root

Common issues

• Run crashed with\

  terminate called after throwing an instance of 'std::future_error'
    what():  std::future_error: No associated state
  DeviceFind: Failed scanning the PCI bus.
  Error: 0xffffffffffffffff - Unrecognized error code
  

  
  This is caused by the WinDriver module not being installed (e.g. the machine was rebooted). It is solved by running the configureOnBoot-windriver.sh script as root (using the ksu command), available under sbndaq-artdaq/Generators/SBND/NevisTPC
