Timeline of ACIS• 1978 first X-rays on a WFPC Chip
• 1984 Proposal for ACIS submitted
• 1985 NASA Selects ACIS
• 1985 Select MIT over JPL for management
• 1988 Drop TI as CCD source, go to LL
• 1988 ASTRO-D (ASCA) test bed for LL CCDs
• 1988 Review before Phase C/D contract
• 1989 Slow start,
• 1990 Settled on LL CCD design
• 1992 Descope to high orbit and 4 mirrors, 2 FP instruments.
• 1994 Final CCD design and flight unit production starts
• 1995 Crisis on schedule, William Mayer takes over as Project Manager, MIT goes into crisis mode.
• 1995 Decide to use 2 chip for initial calibration
• 1996 Only two BI chips good, use on S3, S1
• 1996 Cracks in filters, change to polyimide and recalibrate
• 1996 Flexprint failures, need to fix CCDs on flight paddles
• 1997 Contamination on CCDs in cal at MIT
• PSU microprobe shows low Na and K
• 1997 Calibration of 2C and flight unit
• 1997 Vac test of full instrument on SIM
• 1998 Full test of S/C TV at TRW, ACIS door fails to open
• 1998 Design safety for door opening
• 1999 All door tests look good, no test in STS before deploy
• 1999 Launched
