Abstract

The challenging performances requirement placed on the Earth Observing System (EOS) SOLar Stellar Irradiance Comparison Experiment II, part of the SOlar Radiation and Climate Experiment (SORCE), is to measure the solar irradiance from 115 nm - 320 nm to within 5% of its absolute value, with a 0.5% per year relative accuracy for a mission life of 5 years. The integrated flight Photomultiplier Tube (PMT) detector package developed for these instruments contains a PMT, PMT housing, high voltage divider, pulse amplifier discriminator (PAD) and high voltage power supply. This paper summarizes the results of laboratory measurements that were made on the performance characteristics of the detectors systems selected for flight. These measurements include pulse height distribution, quantum efficiency, photocathode uniformity, photocathode temperature response for both Cesium Iodide and Cesium Telluride, as well as, PAD dead-time and light hysteresis.
