Overview
This page gathers information related to high intensity (5 x 107 γ/s) GlueX running.
Reference Material
- L3 min-review Slides (7/22/2016 )
- Level-3 Trigger Meetings
- Constraints from VME and Network Interfaces
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.
- What is the L1 trigger rate expected for 5 x 107 γ/s
- What are the expected data rates for each crate?
- How do the rates scale with beam intensity?
- What fraction of events will be reconstructable/usable?
- Can we reduce the data read from each crate by dropping headers or reformatting? (e.g. fADC125 Trigger Times)
- 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?
