ME1/1 ODMB Production Readiness Review: Schedule and Budget Darien Wood Northeastern University For the ME1/1 Electronics Project
Categories • On-chamber electronics • DCFEBs (504 + spares) • LVDB (72+) • LVMB (72+) • ALCT mezz (72+) • Peripheral crate electronics • OTMB mezz (72+) • OTMB base boards (72+) • ODMB (72+) • Infrastructure • New LV supplies, junction boxes, cables supply to JB • Patch panels • Peripheral crate modification • Optical cables • Signal cables (pads to DCFEB – 40% new)
Where we are today • DCFEB: • Production and testing >50% complete • Expect final production run in ~3 weeks • 14 boards installed in detector in 2 “demonstrator chambers” • OTMB • Mezzanine: production and testing complete • Base board – production fabrication underway, all parts in hand • 2 production mezzanines with old base boards installed temporarily for demonstrators • ODMB • First prototype (2012) • Only designed for optical TTC (anticipating FF_EMU ASIC, since abandoned) • Limited capability for interfacing with DCFEB, but able to read out optical data path • Second prototype (April 2013) • Fully functional design • Boards at UCSB, OSU, Rice and CERN • Used for some STEP tests for testing chambers after refurbishing • Used to read out 2 demonstrator chambers • Preproduction starting (10 boards, production design)
ME1/1 Installation Schedule • Selected items from TC1 schedule (11-Sep-2013) • ODMB boards go into Peripheral VME crates • Do not have the installation constraints of on-chamber electronics • While waiting for final ODMB production, use prototype v2 boards and preproduction boards for commissioning • Have 10 v2 boards, making 10 pre-production boards
ODMB pre-production and final production • Production procurement was begun on 27-Aug • Expect complete parts Nov-Dec • Parts for 10 preproduction boards should be in hand next week • Used alternate source for smaller quantity of FPGA’s • Want pre-production board at CERN as soon as possible • Commissioning • Long Term Test Stand
Schedule elements • October 10: All components for first 10 boards delivered to Pactron. • October 11: Begin production of first 10 boards. • November 1: First 10 boards arrive at UCSB. • November 8: First 5 boards tested at UCSB, some shipped to CERN. • November 15: Boards 5-10 tested at UCSB, more shipped to CERN. • November 8: All components delivered to Pactron. • December 1: Begin production of remaining 80 boards. • January 1: Remaining boards begin arriving at UCSB. • February 1: Finish production testing of boards at UCSB
Schedule risks • Delay in delivery of parts (08 Nov → 08 Dec) • Lost time over Dec/Jan holidays • Production start → 10 January • Production testing slower than assumed (4/day → 2/day)
Schedule elements with pessimistic assumptions • October 10: All components for first 10 boards delivered to Pactron. • October 11: Begin production of first 10 boards. • November 8: First 10 boards arrive at UCSB. • November 21: First 5 boards tested at UCSB, ship some to CERN. • December 1: Boards 5-10 tested at UCSB, more shipped to CERN. • December 8: All components delivered to Pactron. • January 10: Begin production of remaining 80 boards. • February 10: Remaining boards begin arriving at UCSB. • March 20: Finish production testing of boards at UCSB.
ODMB cost details 72 boards + 18 spares = 90 boards Single costs (setup, testing, shipping): $ 3750 Test equipment: $7500 Cost increment for first 10 boards: $2900 (may be a bit more) Total production cost estimate: $220k (includes pre-production) Estimate from July 2013 change request: $234 k
