Technical Papers and Presentations

In ESA's Cosmic Vision program, the Japanese SPICA satellite is a mission of opportunity in the M-class, with the SAFARI instrument being one of the next generation space-borne astronomy instruments being developed to take advantage of SPICA’s cryogenically cooled 3-m class primary mirror. The SAFARI instrument will use large-format arrays of Transition Edge Sensor (TES) bolometers read-out with Frequency Domain Multiplexing (FDM) and operating at 50 mK.

These TES detectors use the transition in resistivity between the superconducting and normal state to sense the deposited power. The purpose of this programme is to demonstrate the required magnetic shielding for a realistic detector configuration. We describe the magnetic shielding models created in COMSOL Multiphysics® and compare the modelling results with measurements performed on test shields.
