Low power hybrid circuits for satellite-borne time of flight spectrometers
Abstract
A charge sensitive amplifier and an input discriminator for a time amplitude converter were developed for time of flight spectrometers, and tested as thin film hybrids. Time of flight spectrometers are very important tools for analyzing the ion composition of planetary and interplanetary magnetized plasma populations. The particle mass is obtained from simultaneous measurements of the particle energy and velocity. Application of this technique in satellite instruments requires low mass and low power circuits. The amplifier weighs 1.9 g and has a power consumption of 6.8 mW. The hybrid weighs 2.9 g with 100 mW power. The time walk is smaller than 200 psec over a dynamic range of more than 30.
