Overview

This page gathers information related to high intensity (5 x 107 γ/s) GlueX running.

Planning

Near-term Questions

Here is a place to gather some questions that need to be answered in order to properly plan for high intensity running.

  1. What is the L1 trigger rate expected for 5 x 107 γ/s
  2. What are the expected data rates for each crate?
    • How do the rates scale with beam intensity?
  3. What fraction of events will be reconstructable/usable?
  4. Can we reduce the data read from each crate by dropping headers or reformatting? (e.g. fADC125 Trigger Times)
  5. Can we reduce the data read from each crate by reducing readout windows?
    • Do the tagger data rates really drop below the FDC when the windows are reduced?
