Paper Abstract

This paper describes an implementation of a recently developed charge amplifier, called Integration Amplifier, in the UKIRT 7 channel spectrometer (CGS2), resulting in the conversion of the CGS2 from the traditional transimpedance amplifier to a commercial charge integration scheme. Also described is a new data acquisition system; the news system allowed the implementation of a noise reduction algorithm which is a mojor factor in the improved sensitivity of CGS2. The noise reduction algorithm is presented together with a system diagram of CGS2.
