Spectroscopic Investigation of Nebular Gas (SING): instrument assembly, testing and calibration

On demand | Presented live 17 June 2024

Abstract

SING is a near ultraviolet (NUV) spectrograph designed to operate from 1400 Å to 2700 Å with a spectral resolution of around 3.7 Å. The primary science objective is to study the physical conditions in extended regions of the sky like the ISM, supernova remnants (SNR) and planetary nebulae. SING has a telescope with a primary aperture of 298mm, which collects and feeds to a long-slit UV spectrograph. The spectrograph employs a dumbbell slit and a holographic flat-field-corrected concave grating to image the slit at different wavelengths onto the detector. SING employs a photon-counting detector based on an image intensifier and CMOS camera. The spectrograph is intended to map nebulae and other extended objects at moderate spatial and spectral resolution in the NUV from a stable platform of the space station -- Chinese modular space station (CSS). In this work, we present the instrument's optomechanical alignment and assembly, followed by testing and calibration.

Bharat Chandra P is a PhD student at the Indian Institute of Astrophysics (IIA). He received his MTech degree in astronomical instrumentation from Calcutta University in 2019. His research interests are UV instrumentation, high-altitude ballooning, and optoelectronic instrument design. He has worked on the StarberrySense, a Raspberry Pi-based star sensor flown on the experimental module on the 4th stage of the PSLV C-55. He is currently working on the development of SING, A UV spectrograph which focuses on studying extended objects like interstellar medium (ISM), supernova remnants and planetary nebulae.
