MINER A NuMI MINER A DAQ Review 12 September 2005 D. Casper UC Irvine September 12, 2005Electronics and DAQ3 WBS 7.2 & 7.3: DAQ CROCs and DAQ (7.2, 7.3) t One CROC per 48 MAPMTs »Each CROC controls 4 LVDS chains of 12 MAPMTs t Three VME crates + computer »Two crates for CROCs »One crates for auxiliary electronics t Front-end/computer interface t Distribute trigger and synchronization from NuMI t Monitor and control MAPMT high- voltages t Configure front-end electronics

MINER A NuMI MINER A DAQ Review 12 September 2005 D. Casper UC Irvine September 12, 2005Electronics and DAQ4 Specifications Synchronization t Measure global time (between front-end boards) to a few nanoseconds Trigger t Tap into NuMI timing signals through MINOS Readout t Handle rates up to 1 kHz (for PMT testing and calibration) Control t MAPMT HV control and monitoring t Configuration of front-end board firmware

MINER A NuMI MINER A DAQ Review 12 September 2005 D. Casper UC Irvine September 12, 2005Electronics and DAQ5 Design Issues and Concerns CROC Design t Not technically challenging, but requires EE time Triggering and Synchronization t Need to flesh-out interface with NuMI and MINOS t Understand what auxiliary electronics are required t Investigate possibility of self-triggering »Firmware issue? Readout t Requirements for PMT testing unspecified t Requirements for Veto Wall unspecified

MINER A NuMI MINER A DAQ Review 12 September 2005 D. Casper UC Irvine September 12, 2005Electronics and DAQ6 Progress to Date/Near-Term Plans Progress t LVDS chaining tested successfully (between front-end boards only) t Protocol and Frame for LVDS communications successfully tested (Christian Gingu) »Designed to be forward compatible with full required functionality Near Term Plans t Begin design of CROC prototype as soon as possible t Procure VME system for testing and writing low-level readout software

MINER A NuMI MINER A DAQ Review 12 September 2005 D. Casper UC Irvine September 12, 2005Electronics and DAQ8 Cost and Schedule Overview (II) Current schedule is out of date t e.g. CROC design did not begin on 6/1/05 and will not be completed on 9/20/05 Projected Schedule t CROCs: »Should begin design as soon as possible »Finish production and testing of prototype by July ’06 t VME Readout System »Procurement of VME test system scheduled for October 2005 »Need to complete paperwork for UC Irvine MoU, etc.

MINER A NuMI MINER A DAQ Review 12 September 2005 D. Casper UC Irvine September 12, 2005Electronics and DAQ9 Cost and Schedule Issues and Concerns PMT Testing (WBS 6) Drives Our Schedule t Need to understand required components and coordinate schedules t M&S costs for CROC prototypes (7.2.3) underestimated (need more than two) Auxiliary Electronics t MINOS timing module for NuMI synchronization not explicitly included in WBS Veto Wall DAQ Requirements (if any) Unspecified Electronics Design t Paul is unavailable until roughly 1/06 t Design of CROC prototype should start as soon as possible t Should request EDIA time from another EE

MINER A NuMI MINER A DAQ Review 12 September 2005 D. Casper UC Irvine September 12, 2005Electronics and DAQ10 Conclusions Base Cost: $349,464 (total, no contingency) t M&S: $210,310 t Labor: $139,154 t Need to update after confirming the number of prototypes needed Highest Contingency Items: t CROC production: 50% $48,000 = $24,000 »Need a concrete design t Other M&S contingencies are nominally 20% »Based on old quotes, need to update t Unspecified auxiliary electronics »No big-ticket items, but potentially a number of smaller ones Schedule Risks: t CROC design should begin as soon as possible, in parallel with front-end work »Not a significant technical risk t Only serious constraint is PMT testing »Understand the WBS 6 schedule and requirements
