Cosmic RAy Telescope for the Effects of RadiationCRaTER Pre-Ship Review(I-PSR)Instrument ConfigurationBob GoekeJanuary 3-4, 2008Cosmic RAy Telescope for the Effects of RadiationSerial Number 1 -- Flight Spare• First to start into manufacturing– Problems with FPGA lead forming caused delay in completion• Removed 28VDC housekeeping sense lines to be identical to SN2• Unit does not have Dosimeter• Fully Qualified, except– EMC waivers; this unit did not see CE01, CE03 testing (ref. RFA-PER-1,3); turn-on transient– Contamination Inspection at GSFC– Shock and Acoustics deferred to Orbiter level• Sub-assembly identification– Electronics Ass’y: sn 001• Analog PCB Ass’y: sn 005• Digital PCB Ass’y: sn 001F– Telescope Ass’y: sn 003• PCB Ass’y: sn 003• Detectors D1-D6: D006, E005, D007, E006, D008, E007• Operating Hours to 12/21/07: 188:46 on; 119:35 vacuum; 149:54 trouble-free (1000/200/350)Cosmic RAy Telescope for the Effects of RadiationSerial Number 2 -- Flight Unit• Was qualified for Vibration & Thermal-Vac• Failed EMI -- RE02• Reworked (removal of housekeeping sense lines on 28VDC bus); EMC retest• ReQualified by 1 axis Vibration and 1 cycle Thermal-Vac• Fully Qualified, except– EMC waivers; turn-on transient– Contamination Inspection at GSFC– Shock and Acoustics deferred to Orbiter level• Sub-assembly identification– Electronics Ass’y: sn 002• Analog PCB Ass’y: sn 004• Digital PCB Ass’y: sn 002F– Telescope Ass’y: sn 002• PCB Ass’y: sn 002• Detectors D1-D6: D003, E001, D004, E008, D005, E011• Operating Hours to 12/21/07: 372:29 on; 223:15 vacuum; 113:39 trouble-free (1000/200/350)Cosmic RAy Telescope for the Effects of
