DAQ and Electronics Summary

• The primex experiment will utilize fastbus technology to digitize signals from all of it's detector systems (HYCAL, tagger, PS, ...) This equipment was used successfully during the August 2002 beam test.

• The primary physics trigger will be implemented using UVA designed , NIM standard modules (UVA120A and UVA125A). The trigger will occur when 2 clusters separated by at least 10cm are present in HYCAL. Simulation studies indicate high efficiency with little sensitivity to thresholds.

• All modules and crates are currently on site and are in possession.

• Primex will take production data with an event rate of approximately 3kHz and an data rate of approximately 7.3MB/sec.

• Over 50K lines of code has already been written for primex. Approximately 30K lines of this is specifically for data analysis and online monitoring.
