WBS 7.2 & 7.3: DAQ
CROCs and DAQ (7.2, 7.3) One CROC per 48 MAPMTs
» Each CROC controls 4 LVDS chains of 12 MAPMTs
Three VME crates + computer» Two crates for CROCs
» One crates for auxiliary electronics Front-end/computer interface Distribute trigger and synchronization

Specifications
Synchronization Measure global time (between front-end boards) to a few nanoseconds
Trigger Tap into NuMI timing signals through MINOS
Readout Handle rates up to 1 kHz (for PMT testing and calibration)
Control MAPMT HV control and monitoring Configuration of front-end board firmware

Design Issues and Concerns
CROC Design Not technically challenging, but requires EE time
Triggering and Synchronization Need to flesh-out interface with NuMI and MINOS Understand what auxiliary electronics are required Investigate possibility of self-triggering
» Firmware issue?
Readout Requirements for PMT testing unspecified Requirements for Veto Wall unspecified

Progress to Date/Near-Term Plans
Progress LVDS chaining tested successfully (between front-end boards only) Protocol and Frame for LVDS communications successfully tested
(Christian Gingu)» Designed to be forward compatible with full required functionality
Near Term Plans Begin design of CROC prototype as soon as possible Procure VME system for testing and writing low-level readout software

Cost and Schedule Overview (II)
Current schedule is out of date e.g. CROC design did not begin on 6/1/05 and will not be completed on
9/20/05
Projected Schedule CROCs:
» Should begin design as soon as possible
» Finish production and testing of prototype by July ’06 VME Readout System
» Procurement of VME test system scheduled for October 2005
» Need to complete paperwork for UC Irvine MoU, etc.

Cost and ScheduleIssues and Concerns
PMT Testing (WBS 6) Drives Our Schedule Need to understand required components and coordinate schedules M&S costs for CROC prototypes (7.2.3) underestimated (need more than
two)
Auxiliary Electronics MINOS timing module for NuMI synchronization not explicitly included
in WBS
Veto Wall DAQ Requirements (if any) Unspecified Electronics Design
Paul is unavailable until roughly 1/06 Design of CROC prototype should start as soon as possible Should request EDIA time from another EE

Conclusions
Base Cost: $349,464 (total, no contingency) M&S: $210,310 Labor: $139,154 Need to update after confirming the number of prototypes needed
Highest Contingency Items: CROC production: 50% $48,000 = $24,000
» Need a concrete design Other M&S contingencies are nominally 20%
» Based on old quotes, need to update Unspecified auxiliary electronics
» No big-ticket items, but potentially a number of smaller ones Schedule Risks:
CROC design should begin as soon as possible, in parallel with front-end work» Not a significant technical risk
Only serious constraint is PMT testing» Understand the WBS 6 schedule and requirements
