ACIS Relocation of Flight Hardware Simulator

1. ACISRelocation of Flight Hardware Simulator CXC Quarterly Review 23 April 2014 Gordon Garmire (Principal Investigator) Presented by Peter Ford

2. Overview • What is to be moved? • Flight hardware simulator • Peripheral equipment • Spare hardware • People and documentation • Who is moving it? • ACIS personnel • Outside contractor • When is it to be moved? • Current schedule • Fall-back schedule • What are the associated risks? • Likelihood/impact assessment • Additional material • Engineering unit components MKI:PGF

3. What is to be moved? • Flight Hardware Simulator • Detector electronics assembly (DEA: 10 video processors + 2 interface cards) • Digital processor assembly (DPA: 6 front-end- and 2 back-end-processors) • Power supply and mechanism control (PSMC) • Peripheral Equipment • L-RCTU interface between computer and DPA • Image loader: frame buffer to simulate DEA output into DPA • Pixel switch to switch DPA input between DEA and image loader • PSMC push-button control unit • Spare Hardware • Replacement hardware and cabling for all of the above • Spare focal-plane assembly • People and Documentation • The MIT ACIS engineering team: 6 full-time employees • Document archive including ITAR/EAR-restricted items • Software configuration system and library of previous regression tests MKI:PGF

8. Who is performing the move? • Management • Brian Surette, MKI Facilities/Safety Manager • Sudy Nally, Project Manager, MIT Facilities • Core Hardware and Documentation • Jim O’Connor, ACIS Project Technician • Bob Goeke, Senior Research Engineer • Demitrios Athens, Research Staff • Peripherals, Testing • Demitrios Athens, Research Staff • Royce Buehler, Research Staff • Peter Ford, Principal Research Scientist • MKI IT Network • Demitrios Athens, Research Staff • MKI Network Staff • Office Contents • Contractor: Fox RPM Corp. • Telephones, MIT WiFi Network • MIT Network Services MKI:PGF

9. The Master Plan 157 Items to be moved to NE83 34 Items to be moved elsewhere or left in place MKI:PGF

10. The Building Plan Freight Elevator 5th Floor — Offices and Meeting Rooms Elevators Flight Assembly ACIS 4th Floor — Laboratories and Flight Assembly MKI:PGF

11. 2014 Schedule • January - March • Complete demolitions • Complete framing of new walls • Rough-in and inspect electrical and plumbing • April – Mid-June • Complete walls, electrical and plumbing • Install and test MKI network • Install telephone and WiFi network • June 14-15 (weekend) • Move heavy equipment (with rigs and hoists) • June 19-20 (after 6 pm) • Move offices, IT servers and light equipment • Move ACIS documents and drawings • June 21-22 (weekend) • Continue moving light equipment • Move ACIS engineering unit and peripherals • June 28-29 (weekend) • Continue moving heavy equipment (if necessary) MKI:PGF

12. Detailed ACIS Schedule • Early June • Move duplicate ACIS peripherals to NE83 • Install duplicate clean tent • Test ACIS peripherals and internet interface • Move and test duplicate ACIS web server • Late June • Move ACIS engineering unit • Connect to duplicate peripherals and test • Estimated “down time” less than 24 hours • Move remaining peripherals, clean tent, and web server • Move ACIS document vault • July, August • Should the schedule slip, the above steps can be delayed until as late as mid-August, subject to the following: • MKI staff will be increasingly busy delivering a flight instrument • ACIS engineering unit will be needed to certify A016 SI modes MKI:PGF

13. Risk Assessments • Engineering Unit Risk Assessment • MIT 36–02407 Revision A, September 25, 2011, submitted to SAO 9/27/11 • Conclusions • Existing physical security in NE80 is adequate • Some ACIS hardware items lacked sufficient replacements • As a result, the following mitigations have been applied: • Additional DEA flight-spare video board built and tested • Replacement 28V power supplies ordered • Replacement 24V, 15V and 5V power supplies acquired • All parts required for replacement DEA and DPA backplanes kitted • Updated Risk Assessment during and after the move • MIT 36–02407 Revision B is in preparation • Damage to the EU or peripherals during the move is judged unlikely and is mitigated by the availability of replacement parts for all units, cables, etc. • Current hardware re-test plans are adequate • Our objective is to match the level of physical security achieved in NE80; implementation plans are not yet complete • Should the EU be irreparably damaged, it may be hard to develop flight software patches or investigate flight hardware anomalies, but software has been developed to validate uplink loads for science and calibration runs MKI:PGF

14. Original Risk Assessment Conclusion: only item 18 required further analysis and mitigation MKI:PGF 23 April 2014 14

15. Risk Mitigations • † Mitigations: • Replacement DEA and DPA backplanes and connectors assembled • Power supplies acquired and cables made up to replace PSMC MKI:PGF
