Frequency Shift Algorithm: Design of a Baseband Phase Locked Loop for Frequency-Domain Multiplexing Readout of X-ray Transition-Edge Sensor Microcalorimeters
Paul van der Hulst, Jan van der Kuur, Ad Nieuwenhuizen +5
The Transition-Edge Sensor (TES) is an extremely sensitive device which is used to measure the energy of individual X-ray photons. For astronomical spectrometry applications, SRON…
Josephson effects in an alternating current biased transition edge sensor
Luciano Gottardi, Alex Kozorezov, Hiroki Akamatsu +10
We report the experimental evidence of the ac Josephson effect in a transition edge sensor (TES) operating in a frequency domain multiplexer and biased by ac voltage at MHz frequen…
Multiplexed readout demonstration of a TES-based detector array in a resistance locked loop
Jan van der Kuur, Luciano Gottardi, Mikko Kiviranta +5
TES-based bolometer and microcalorimeter arrays with thousands of pixels are under development for several space-based and ground-based applications. A linear detector response and…
