Evaluation of Controllers and Development of a New In-House Controller for the Teledyne HxRG Focal Plane Array for the IRSIS Satellite Payload

The Infrared Astronomy Group (Department of and Astrophysics) at Tata Institute Fundamental Research (TIFR) is presently developing controllers for the Teledyne HxRG Focal Plane Arrays (FPAs) to be used on board Spectroscopic Imaging Survey (IRSIS) satellite payload. In this paper, we discuss results our tests with different FPA such as Astronomical Cameras (ARC) controller, Teledyne’s SIDECAR ASIC well new in-house designed Array controller. As part development phase IRSIS instrument, which an optical fiber-based Integral Field Unit (IFU) Near-Infrared (NIR) Spectrometer, a laboratory model limited NIR bandwidth was built consisted various subsystems like Ritchey–Chretien (RC) 30[Formula: see text]cm telescope, fiber IFU, spectrometer optics, H2RG detector module. We developments during building testing technical aspects prototype
