GlueX Start Counter Meeting, March 19, 2015, Minutes

  * *FIU*: Werner Boeglin
  * *JLab*: Mark Ito (chair), Eric Pooser, Beni Zihlmann


Detector Status

Eric gave the report.

  * There are three channels with higher than normal rates in the
    discriminator-based scalers (no beam). The standard rate is about 10
    Hz, these are going at 500 Hz.
  * Eric is working on an automated program to do discriminator
    threshold curves. this may troubleshoot the previous item. He wants
    to implement a similar program that used the FADC-based scalers.


Calibration

  * Eric has done a lot of work calibrating time-walk for the start
    counter. He will give a presentation and next week's Calibration
    Meeting.
  * Eric plans to start work implementing propagation delay corrections
    based on the measurements made on the bench at FIU. At present Simon
    has implemented a simple velocity based correction in the code.


Online Monitoring Histograms

There are several improvements to the online monitoring histograms that 
Eric has planned. He will turn to this after the propagation delay 
constant work.
