  1. THEMIS INSTRUMENT SUITE • FM2/FM3 PRE-SHIP REVIEW • FM4/FM5 PRE-ENVIRONMENTAL REVIEW • ESA • Dr. Chuck Carlson • University of California - Berkeley

  2. Outline • Summary of ESA Status at FM2/3 PSR and FM4/5 PER • Final Test and Cal Results vs. Requirement Fulfillment • PFRs • Open Items

  3. ESA Status • Requirements and Design: • No major changes to Requirements or Design since M-CDR • No RFAs from previous reviews outstanding • Procurement: • All procurement is complete. • Assembly and Test: • 5 ESA mechanical assemblies complete • 6 sets of High Voltage power supplies complete and tested • 6 HV mother boards assembled and tested with HV supplies • 12 anodes (6 sets) assembled and tested with MCPs • 5 Preamp boards complete; 3 tested in complete units • 5 HV Interface boards complete; 3 tested in complete units • FM1-FM5 assembled • FM1-FM2 calibrated • 6 LVPS built and tested

  4. ESA Requirements • ESA Mission Requirements Fulfillment: • MRD fulfillment noted in THEMIS Verification Matrix (see MSE Presentation) • Integrated ESA and component parts compliant with mission requirements

  5. Results of FM2 ESA Calibration • Energy/Angle response confirmed • MCP Gain characteristics tested and successful • MCP Noise – working on fixing low level noise issue • Anode response tested and confirmed • End-to-end performance has been verified

  6. PFR Status • ESA PFR List: • All ESA PFRs have been Closed except PFR 071 (spare) and PFR 106 • PFR 106 – currently testing modified grounding scheme to eliminate noise pick-up

  7. Open Items • ESA Calibration check still to be done • ESA calibration confirmation after Environmental Testing
