GlueX Start Counter Meeting, January 22, 2015, Minutes

Present:

  * *FIU*: Werner Boeglin
  * *JLab*: Mark Ito, Eric Pooser, Simon Taylor, Beni Zihlmann


Announcements

  * The next collaboration meeting is coming up. FIU will start thinking
    about what to present.
  * The final invoice from FIU on the construction contract is in the mail.


Review of Minutes from the December 12 Meeting

We went over the minutes 
<https://halldweb1.jlab.org/wiki/index.php/GlueX_Start_Counter_Meeting,_December_12,_2014#Minutes>. 


  * Eric will provide feedback to Justin Stevens on the offline
    monitoring histograms.
  * The anomalously low rate in sector 2 is still not understood.


Reconstruction and Calibration

Eric gave an update.

  * Mahmoud Kamel is working on the timing calibration.
  * Eric is working on the hit position correction to timing.
  * Eric, Simon, and Paul Mattione are looking at the previously
    reported anomaly at 180 degrees in azimuth. No
    charged-track-start-counter matches are found for three counters in
    that region. The start counter hit seems present, the charged track
    is pointing to it, but the match is not registered.
  * In the r-z view the intersection of tracks with the start counter
    shows a large number of points that are outside the physical
    counters, clearly a bug. Werner thought that this should be
    addressed first.


Plans for Spring Run

We went over the list of tasks 
<https://halldweb1.jlab.org/wiki/index.php/TOF_DAQ_Tasks,_January_22,_2015> 
that Mark had put together for the TOF. Since these are mostly generic 
they served as a useful list for the start counter as well. We agreed 
that many of them should be pursued and that the next step is to 
prioritize the list.
