present: Sergey Boyarinov, Stepan, Nathan, Valery, Ben


1. RG-F run status

  • DAQ event rate is only few kHz, data rate significantly below 100MB/s because of gas target, with beam current 250nA
  • trigger is electron with drift chamber roads and 300MeV EC threshold, seems sufficient for production running
  • big dead time produced by RTPC readout, cannot run faster then about 1.5kHz if desired lifetime is above 90%
  • beam current unlikely to be increased, so we will stay with current settings for entire run


2. Streaming DAQ progress

  • still need to fix VTP TCP/IP issues (Ben)
  • reconstruction algorithms to be considered for online data processing: offline code, level1 code, ...; can be tested as 'level3' in current DAQ
