PHENIX Run 13 Status and Luminosity Update - 14 May 2013

This report provides an update on the status of the PHENIX experiment from the Run 13 at RHIC. It includes the efficiencies of the collaboration as of 14 May 2013. The Luminosity to date and the performance of the Silicon luminosity counters in the specified rapidity range are discussed. Details on self-triggered data streams into FPGAs are covered, along with configurations for selecting single hits and hit pairs in phi segments. Additionally, the hit-scaled scalars for √S = 510 GeV p-p data and statistical errors are reviewed.

  1. PHENIX Run-13 status Hubert van Hecke for the PHENIX collaboration Time - 14 May 2013

  2. Phenix efficiencies Time - 14 May 2013

  3. Luminosity to date Time - 14 May 2013

  4. Silicon luminosity counters 1.2<eta<2.4 48 segments in phi 2 segments in z Can select single hits in a phi segment, Or hit pairs in a phi segment How it is done: self-triggered data streams into FPGAs (max 2Tbits/s), where hits are formatted for the event data stream. There is enough space left in the FPGAs to split the incoming stream and set up luminosity counters.
