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
- event rate/data rate were added to DAQ/Trigger EPICS GUIs
- MPOD power supply has some issues - Nathan
- logbook GUI insertion policy may be reconsidered - too many GUIs in logbook
- some network switches keeps dying, replacement installed already on FC, moving wires there; port 48 is set to 10MBit/fullduplex for etherlite32
- trigger bit names should be in trigger GUI, Ben/Valery will implement it
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
- will investigate different aspects: DAQ (ben,sergey), reconstruction (sergey,gagik), physics motivation/needs (vpk,stepan), human abilities to run reconstruction online, etc
- level3 seems good place to investigate possibility to run reconstruction online
