PHOBOS Trigger and DAQ
Low and high h trigger counter (Cerenkov; low also used as timing for TOF wall)
Data rate is 200 Hz (30 % centrality and 18 Kbytes/event)
=> 60 - 430 TByte/year !!!
Limited by data recording capability, data storage and CPU time for all four experiments
MIT-designed pipeline chip provides continuous data flow
