Since their development in the late 1960s, CCDs have revolutionized observational astronomy. But poor performance at UV wavelengths, coupled with historically high noise, have required the development of alternative detectors for UV telescopes and instruments. These alternatives, including micro-channel plate detectors of the type used on GALEX, still achieve low quantum (<10-20%) efficiency, and pose their own set of unique hardware challenges in flight. Here we report on the development of a second generation UV detector which is predicted to achieve QEs of over 60% in the space ultraviolet. This high efficiency may be reached by modifying a backside illuminated delta-doped Low Light Level (L3) CCD with a thin film, in the manner of an anti-reflection coating. Increased transmission into the Si subsrate from the coating and the extremely low read-noise of L3 CCDs help to boost efficiency. Preliminary testing has shown great promise for this method. Furthermore, we detail the specific use of this detector in a spectrograph optimized for UV wavelengths from 100nm to 300nm, with particular emphasis on the next generation spectrograph to be flown as part of the FIREBall balloon payload.
