===Simulated HDDM to EVIO Conversion===

 +
Sean has enhanced the fix to the [[GlueX_Offline_Meeting,_September_17,_2014#100_ns_Shift_Issue:_an_effective_time_cut|100-ns-Shift/effective-time-cut issue]] by adding a cut on the maximum time that will appear in the EVIO-formatted file. This emulates the hardware in that the time window read-out need not correspond the time window generated in simulation. This change was prompted by Kei noticing that the number hits from the Time-of-Flight in simulated data often exceeded the maximum set by the convert-to-EVIO program. This in turn was due to the 1.6 &mu;s window in recent simulated data to capture all hits in tracking chambers with their long drift times. Each detector system has an independently adjustable time window now.

Review of Minutes from October 15

We went over the minutes from the last meeting.

Simulated HDDM to EVIO Conversion

Sean has enhanced the fix to the 100-ns-Shift/effective-time-cut issue by adding a cut on the maximum time that will appear in the EVIO-formatted file. This emulates the hardware in that the time window read-out need not correspond the time window generated in simulation. This change was prompted by Kei noticing that the number hits from the Time-of-Flight in simulated data often exceeded the maximum set by the convert-to-EVIO program. This in turn was due to the 1.6 μs window in recent simulated data to capture all hits in tracking chambers with their long drift times. Each detector system has an independently adjustable time window now.

Version Management

Mark gave a talk at last week's Calibration Meeting on his software-version specification system. The system has been incorporated into the current GlueX Install system.

itrack, track, and the Truth

We decided to postpone discussion of this change until either Richard or Justin can lead it.

BCAL Dark Noise Hits

Will and David explained the current problem with dark noise hits in the BCAL. The rate is about right but our assumption about the amplitude of the hits is off. In addition the calibration scheme subtracts dark energy from the hits.

The plan is to take real data with a random trigger to assess the real situation now that the BCAL in installed and instrumented.

This will be discussed at the BCAL Reconstruction Meeting tomorrow.

Commissioning Simulations

Sean presented preliminary rate estimates from his analysis of recent EM-background-only simulations with the commissioning geometry. See his slides for the plots. Assumptions:

  • 100 nA electron beam
  • 10 μm Al radiator
  • 2 mm plastic target

Rates are presented in kilohertz for both field on (1200 A) and field off. Estimates for all detector systems are included.

Sean also reviewed a recent email from Richard Jones on how to convert the number of hits in the simulation runs to detector rates with the given conditions.

Offline Data Monitoring

Paul M. moderated the discussion.

  • David is working on a scheme to copy root files from the Gluon Cluster to the work disk in the Computer Center so they can be viewed on the web.
  • Simon had updated several code components for the PS
    1. geometry in HDDS
    2. hit routines in HDGeant
    3. sim-recon hit objects for PS and PSC
    4. monitoring histograms for online monitoring
    • Digi-hits have not been addressed yet.
  • Kei reported on work establishing the online monitoring histogram generation in the offline environment.
    • No plugins yet for TAGM
    • FDC plots have been added

    • He is in the process of writing and testing scripts for running offline monitoring.
  • Paul reported for Justin. There have been improvements in the web pages for viewing offline monitoring data to improve the user experience. See the links below.
