Digital frequency multiplexing with sub-Kelvin SQUIDs
Amy E. Lowitz, Amy N. Bender, Matthew A. Dobbs +1
Digital frequency multiplexing (dfMux) is a readout architecture for transition edge sensor-based detector arrays and is used on telescopes including SPT-3G, POLARBEAR-2, and LiteB…
Observations of Fast Radio Bursts at Frequencies down to 400 Megahertz
FRB Collaboration, Mandana Amiri, Kevin Bandura +52
Fast radio bursts (FRBs) are highly dispersed millisecond-duration radio flashes likely arriving from far outside the Milky Way galaxy. This phenomenon was discovered at radio freq…
Holographic Beam Mapping of the CHIME Pathfinder Array
Philippe Berger, Laura B. Newburgh, Mandana Amiri +32
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) Pathfinder radio telescope is currently surveying the northern hemisphere between 400 and 800 MHz. By mapping the large s…
Digital frequency domain multiplexing readout electronics for the next generation of millimeter telescopes
Amy N. Bender, Jean-François Cliche, Tijmen de Haan +7
Frequency domain multiplexing (fMux) is an established technique for the readout of transition-edge sensor (TES) bolometers in millimeter-wavelength astrophysical instrumentation.…
