Remotely adjustable EDTM

Currently set with a a command-line helper go_edtm

  • There is a command-line helper go_edtm to set/readback this PV. (the prescale_GUI does not set it at the moment.)
  • More details are in this log entry: EDTM pulser switched to cdaqpi1 output
    • The RPi that controls this is cdaqpi1 which runs an EPICS softIOC. Ellen B. or Brad S. should be contacted if that device has an issue.
    • Note, at present this only works for the SHMS DAQ. Therefore it works for SHMS singles or coincidence running. For HMS, contact the expert.


Manually settable pulse generator

A version of this will be revived by the xem2 experiment for the HMS singles running.  Ask the experts.  We'll post info ASAP.

  • If the EDTM pulse generator located in rack CH03B06 is reset for any reason, the settings must be restored to the following parameters as outlined in this logbook entry
