  1. WBS 1.03 Readout SystemsScope, Cost and Schedule Gary Varner University of Hawaii

  2. Gary Varner, Belle II Directors Review (Pre CD-2/3) Talk Outline • WBS Element Scope • Performance Requirements • Cost Estimate • Schedule • Risk • Summary

  3. WBS 1.03 Scope (1) • Readout electronics for the iTOP (WBS 1.02), and KLM (WBS 1.04) detector • Design, prototype and evaluation of ASICs and readout boards within Belle-II DAQ environment • Procurement of all components • Assembly, integration and test of sub-detector readout modules • Delivery to sub-detector assembly sites 16-17 January 2013 Gary Varner, Belle II Directors Review (Pre CD-2/3) 3

  4. WBS 1.03 Scope (2) • Firmware for real-time ASIC operation and data flow control and monitoring • FPGA/DSP microcoding for waveform data reduction • Documentation and support of ASICs and readout modules • Low-level software modeling of trigger (tsim) and event buffer overflow prevention logic 16-17 January 2013 Gary Varner, Belle II Directors Review (Pre CD-2/3) 4

  5. Performance Requirements • Operate within the Belle II Trigger and Data Acquisition specifications • Meet the detailed timing and signal processing specifications for the iTOP and KLM sub-detectors • Fabricate using commodity components or processes with high yield and reliability assembly houses • Verify component and integrated module radiation tolerance for the background environment expected 16-17 January 2013 Gary Varner, Belle II Directors Review (Pre CD-2/3) 5

  6. CD-2/3 Cost Estimate – WBS 1.03 16-17 January 2013 Gary Varner, Belle II Directors Review (Pre CD-2/3) 6

  7. Cost Basis of Estimate • Reasonable Cost Range • Make up of cost estimate • 54% of total cost is subcontract of ASIC and circuit board fabrication and assembly • Competitive (commodity) quotes received for all components and assemblies • Engineering labor associated with prototype testing and final acceptance testing • Maturity of the estimate • Majority of remaining cost (67%) is commodity components or processes • Remaining estimate based on engineering estimate for development of calibration system, testing, and interface on mechanical system and actual cost from prototype articles. 16-17 January 2013 Gary Varner, Belle II Directors Review (Pre CD-2/3) 7

  8. Schedule – iTOP Readout • Key drivers/constraints • CD-3 April 2014 to support production readout procurement plan • Pre-tested readout assembled with completed modules for extended cosmic-ray verification prior to Belle II detector installation CR B B CR CR B Beam & Cosmic Tests Preproduction Readout CD-3 Production Readout Module Assembly Install & Commission Periods shown are calendar years 16-17 January 2013 Gary Varner, Belle II Directors Review (Pre CD-2/3) 8

  9. Schedule – KLM Readout • Key drivers/constraints • CD-3 April 2014 to support Scintillator production readout procurement plan • Pre-tested readout assembled with completed modules for extended cosmic-ray verification prior to Belle II detector installation CR w/ COPPER CR Cosmic Ray Tests Preproduction Readout CD-3 Production Readout Module+ Pre-amp Assembly Install & Commission Periods shown are calendar years 16-17 January 2013 Gary Varner, Belle II Directors Review (Pre CD-2/3) 9

  10. Identified Project Risks • One high risk remains • Gary Varner and team in Hawaii are overcommitted and cannot complete all assigned scope on schedule. • Mitigation has been to transfer electronics development and testing scope to other institutions (IU, PNNL, WSU, VT, USC) 16-17 January 2013 Gary Varner, Belle II Directors Review (Pre CD-2/3) 10

  11. Technical Risk Assesment • Performance of switched capacitor array waveform sampling has been well established in various experiments (ANITA, MUEGAMMA) • ASICs fabricated in high-volume, commodity IC vendor lines and are low risk • Module fabrication and QA/QC procedures are industry standard processes and low risk • Concurrent ASIC development cycles increase risk of delays due to design multi-tasking • Mitigate by having more stringent submission reviews with additional external experts • Further reduce stress on design engineering resources by increasing pool of qualified test and evaluation engineering talent 16-17 January 2013 Gary Varner, Belle II Directors Review (Pre CD-2/3) 11

  12. Conclusion • Scope of WBS well understood • Evidence – Performance achieved in beam and bench tests • Final opto-electro-mechanical configuration • Integration with existing Belle II DAQ infrastructure • Costs are known and fit within funding profile • Evidence – Costs defined by bid/vendor quote/similar work • Fits funding profile • Ready for CD-2 and (conditional) CD-3 pending success of recently submitted ASICs 16-17 January 2013 Gary Varner, Belle II Directors Review (Pre CD-2/3) 12
