Purpose
In this document we outline our strategy to develop an online system that meets the design goals listed in Online_Design_Goals and Elton's Hall D Design Goal document (see the DocDB). Here we only list major milestones along this development path. Detailed milestones and assignment of names can be found in Elke's Action Item Tracker and other documents.
Basic Considerations
The complete DAQ (approximately 80 full crates) must be ready for commissioning the complete detector with cosmic or pulser triggers by 1Q FY 2014. First beam to the hall is expected in 4Q FY 2014, with low-rate production data taking expected to start in 4Q FY 2015. High-rate production data taking may start as early as 4Q FY 2016, assuming funds are available to upgrade the detector. Beneficial occupancy of Hall D is expected in summer 2010, counting house in fall 2011. Trigger, DAQ, monitoring, and control systems will be needed starting in early 2011 to check out detector subsystems as they are being installed and commissioned.
Note that the 12 GeV project specifies a beam rate of 10**7 photons/sec, but that we plan an eventual upgrade to 10**8. All components must be designed to be capable of, or upgradable or expandable to, 10**8 running.

Trigger/DAQ Detector Needs
DAQ systems of various sorts will be needed during detector development, construction, and checkout. Below, "parallel" means that parallel or staged event building is needed. "Small" means four crates or less, and "large" means more than four crates. In general, parallel readout is only needed at very high rates, where a single network connection cannot handle all the data.
- Single-crate DAQ systems are needed now (Jul-2007).
- Small systems will be needed by Oct 2008.
- Single-crate with trigger/timing needed for FCAL test Summer 2008
- Large systems will be needed by Oct 2010.
- Parallel, large systems will be needed by Oct 2011.
In all cases the readout crates may be full.
(Elton suggests creating a table of configurations needed...ejw, 14-Aug-2007)
