PFP Instrument Status All PFP Instruments Except SWEA have been delivered, integrated, and tested; supporting environmental tests Issues: –EUV alignment shims not flat re-shimmed, CLOSED –SEP temperature sensor noise Temp sensors relocated; now quiet, CLOSED –SEP Heater noise (from TAME) Plan to shield heaters; works on EM, installed on FM this week? –MAG temperature monitor offset Monitor temperature calibration updated. –Missing Time Update Counter Spacecraft flight software fix planned –SASM/LPW timing offset Phase difference identified (on PFP side) Identified an operational fix, which works on EM but has not yet been tested on FM

SWEA Status High Voltage Discharges and instability in Thermal Vac Reworked instrument to stabilize over temperature and reduce the risk of discharges and reduce the risk of damage should a discharge occur Instrument reassembled and in test: –Test in calibration chamber with high voltage, no issues –Vibrated, no issues –Tested again in calibration chamber, no issues – In thermal vacuum, no problem with first few cycles High voltage powered on Cycle 5 (2/19) with no problems –Post-environmental; calibration next week Pre-Ship Review Friday 3/1; Delivery to LM Monday 3/4, ready for integration after bench test, as soon as the afternoon of 3/5.
