SPACETELESCOPESCIENCEINSTITUTE Status of IDTL

Principles• Serve the interests of staff scientists at STScI and JHU• Obtain best possible measurements• Be impartial• Be on the cutting edge• Offer community service



Milestones Achieved• Funded by STScI Science Staff (2/7/00)• Began first project (8/1/00)• Established staff (6/1/00 - 12/1/00)• Received thermal and motion control systems (9/1/00)• Selected under NASA SITD NRA (9/18/00)• Ordered dewar (12/06/00)• Received Aladdin MUX (11/15/00)• Explored COE (3/1/00 - current)



Proposals• Secured STScI DDRF • Secured JHU internal funding (pending NRA award)• Selected under NASA NRA (pending funding)• Proposed to NASA NRA to test 16 NGST near-infrared

detectors with U. Colorado (not selected)• Proposed to NSF to test 24 2K2 near-infrared detectors

with NOAO (pending)• Began proposal effort for Infrared Detector Center of

Excellence



Target Field Simulation Testbed• 1 1/2 year project to deliver images containg real

detector effects and simulated NGST stellar images based on STScI catalog query

• Images will be delivered to NASA for use in the NGST wavefront sensing and control simulators at JPL and GSFC

• Status: on schedule for 2Q02 completion, first detector data to be obtained 2Q01

Education• Goal: to train students and scientists in using and

designing infrared detector technology• Applied for intern under STScI internship program• In talks with JHU P&A, ECE and APL to train graduate

students• Will place ads for post-docs



Summary• Your lab is funded and up and running• DDRF is being allocated as planned• STScI scientists are encouraged to dream big about

science applications using our infrared detector expertise

• Thank you for your support



Infrared Detector COE• NSF/NASA sponsored (at least)• Distributed with overall management at JHU/STScI• 10 year lifetime with 3-5 year external reviews• Initial focus areas: astronomy, medical, military,

commercial, education• Partnering with Universities, Industry, and

Government
