DAQ Milestones

DAQ systems of various sorts will be needed during detector development, construction, and checkout. Here "low-rate" means that parallel or staged event building is not needed, and "small" means four crates or less.

• Low-rate single-crate DAQ systems are needed now (Jul-2007).
• Low-rate small multi-crate systems will be needed by Summer 2008.
• Low-rate large multi-crate systems will be needed by ????.
• High-rate small multi-crate DAQ systems will be needed by ????.
• High-rate large multi-crate systems will be needed by ????.

(I will poll detector groups to determine their requirements...ejw)

In all cases the readout crates may be full.

The full DAQ (approximately 80 full crates) must be ready for testing the complete detector with cosmic or pulser triggers by ????. First beam to the hall is expected in ????, with low-rate production data taking expected to start in ????, and high-rate production data taking expected in ????.
