Simulations of athermal phonon propagation in a cryogenic semiconducting bolometer
Samantha Lynn Stever, François Couchot, Bruno Maffei
We present three Monte Carlo models for the propagation of athermal phonons in the diamond absorber of a composite semiconducting bolometer `Bolo 184'. Previous measurements of the…
Thermal simulations of temperature excursions on the Athena X-IFU detector wafer from impacts by cosmic rays
Samantha Lynn Stever, Philippe Peille, Marcel Bruijn +5
We present the design and implementation of a thermal model, developed in COMSOL, aiming to probe the wafer-scale thermal response arising from realistic rates and energies of cosm…
Benefits of bolometer Joule stepping and Joule pulsing
Samantha Lynn Stever, François Couchot, Valentin Sauvage +1
We introduce the `Joule stepping' technique, whereupon a constantly-biased bolometer has its bias voltage modified by a small additional step. We demonstrate this technique using a…
A new pulse shape description for particle pulses in a highly-sensitive sub-Kelvin bolometer
S. L. Stever, F. Couchot, N. Coron +2
The next generation of cosmology space missions will be sensitive to parasitic signals arising from cosmic rays. Using a composite bolometer, we have investigated pulses produced b…
