Overview

This is a special one-topic meeting whose goal is to try to understand the event size given the recent simulation results on occupancies, especially in the FDC. Note that the 2002 Hall D design document lists 4kB event size, although it is possible that the FDC itself may take 4kB (or even more). The average event size affects the design of the DAQ system in a number of ways, so this needs to be understood sooner rather than later. Fortunately the DAQ architecture is highly scalable, so accomodating higher event sizes and event rates is not a big problem.

The goal of this meeting is to:

  1. Understand what we know and do not know about event size, occupancies, etc.
  2. Devise a plan to learn what we need to learn

We need to hear about
