Abstract

We have incorporated contemporary grating and detector technologies into the design of a new sounding rocket payload which consists of a slitless, objective grating spectrograph with no transmission elements in the opti-cal train (or detector). Built several years ago, this instrument has an effective collecting area of about 4 cm² and can record spectra of point-like sources at a wavelength resolution of 0.004Å (profile FWITM) and with a sample interval (pixel width) of 0.002Å. It is designed to give continuous coverage over the wavelength range 950 < X < 1150A, a region of immense importance to our research on the interstellar medium. The instrument, called the Interstellar Medium Absorption Profile Spectrograph (IMAPS), has flown on a Black Brant rocket and obtained a spectrum of superb quality on an early-type star, π Scorpii. Data obtained on this flight also demonstrated the excellent response of our imaging detector, which uses an electron-bombarded CCD to register individual photoevents.
