Modal Simulation Framework for the Design and Verification of Future Few-Mode Far-Infrared Spectrometers
B. N. R. Lap, W. Jellema, S. Withington +1
Future far-infrared space missions require highly-sensitive spectroscopy as a primary diagnostics tool. However, these systems are sensitive to straylight, due to the ultra-sensiti…
A Route to Large-Scale Ultra-Low Noise Detector Arrays for Far-Infrared Space Applications
D J Goldie, S. Withington, C. N. Thomas +2
Far-infrared detectors for future cooled space telescopes require ultra-sensitive detectors with optical noise equivalent powers of order 0.2 aW/\sqrt Hz. This performance has alre…
Modelling the Partially Coherent Behaviour of Few-Mode Far-Infrared Grating Spectrometers
B. N. R. Lap, S. Withington, W. Jellema +1
Modelling ultra-low-noise far-infrared grating spectrometers has become crucial for the next generation of far-infrared space observatories. Conventional techniques are awkward to…
Quantum analysis of second-order effects in superconducting travelling-wave parametric amplifiers
Songyuan Zhao, Stafford Withington
We have performed a quantum mechanical analysis of travelling-wave parametric amplifiers (TWPAs) in order to investigate five experimental phenomena related to their operations, na…
Suppressed-gap millimetre wave kinetic inductance detectors using DC-bias current
Songyuan Zhao, Stafford Withington, David J. Goldie +1
In this study, we evaluate the suitability of using DC-biased aluminium resonators as low-frequency kinetic inductance detectors operating in the frequency range of 50 - 120 GHz. O…
The SAFARI Detector System
Michael D. Audley, Gert de Lange, Jian-Rong Gao +9
We give an overview of the baseline detector system for SAFARI, the prime focal-plane instrument on board the proposed space infrared observatory, SPICA. SAFARI's detectors are bas…
