A Good Energy Resolution Channel

All Channels' Energy Resolution

Operation

The neutron generator may only be operated by trained operators. Latest documentation on the DAQ operation and subsequent analysis exists, but is not available in html format. For the records an out-dated version of the DAQ operation instructions is also available.

Software Packages

  • EmcSrcCalOnline: dual-use (online/offline) package containing CalChan and CalFit sub-classes for source calibration.
  • EmcOdfUPCSrcCal: online package containing UPC dataflow code for source calibration and waveform acquisition.
  • EmcSrcCalApps: offline package containing a wide-variety of executables for source calibration operation.
