Astronomical applications of the new Goddard Si:Bi 16 x 16 array camera systemAn improved 4-18 micron array camera system has been developed at NASA Goddard Space Flight Center for astronomical protometry, using 16 x 16 Si:Bi (bismuth dope silicon) accumulation mode charge injection device (AMCID) with 256 active pixels. An astronomical observing program using this device has been carried out. The 16 x 16 device had sufficiently good sensitivity, uniformity and noise characteristics to be used for successful observations at the Steward Observatory Mt. Lemmon 60 and 61-inch telescopes in May 1983, and at the NASA Infrared Telescope Facility (IRTF) at Mauna Kea in August 1983. Initial results indicate that this detector has sensitivity and noise characteristics comparable to other devices from the same generation of Aerojet arrays.
