Session 55 - Space Instrumentation.
Display session, Wednesday, June 12
Tripp Commons,
We describe some results of a study for a possible HST instrument, namely an area spectrograph combined with a simplified version of the High Speed Photometer. The spectrograph samples a two-arcsecond diameter area with up to 37 spectra, each with an angular resolution of 0.14 arcseconds. The spectra, in the visible-red region, are 2000 Ålong and have a resolution of about 50 km/s. The photometer consists of two detectors, one solar blind, one near-UV/visible, with perhaps 7 different broad band filters and a variety of entrance apertures. Both instruments fit in the old HSP enclosure with only minor modifications and make maximal use of existing mechanical and electronic hardware.
