Updates to the Calibration System and Test Cryostat for HIRMES
Abstract
HIRMES is a mid-infrared spectrometer scheduled to fly on NASA's airborne observatory SOFIA in 2021. HIRMES aims to study protoplanetary disks and star formation at high resolutions, up to 100,000, which it achieves with several types of Fabry-Perot Interferometers (FPIs). HIRMES will be evacuated and cooled to 4 K, so it is necessary to test the FPIs in cryogenic conditions and have a system that can be used to measure FPI parameters externally. We present the development of a calibration system that can be used to calibrate FPIs mounted in HIRMES, dedicated to NASA AFRC, as well as a cryostat that will be used at Cornell to test the low-res fixed FPIs in cryogenic temperatures.
