Tunable responsivity and bandwidth in microwave kinetic inductance detectors via readout current nonlinearity
Maclean Rouble, Peter Day, Matt Dobbs +3
Microwave kinetic inductance detectors (MKIDs) are generally read out with microwave readout tones of high enough amplitude to adequately suppress the noise contribution of the fir…
Architecture and Validation of the CRS F-Engine for the CHORD Radio Telescope
Ian Hendricksen, Jean-François Cliche, Matt Dobbs +1
We introduce the design of the t0.technology Control and Readout System (CRS) F-Engine that will be used for the Canadian Hydrogen Observatory and Radio transient Detector (CHORD),…
A High-Bandwidth Backplane for Wideband Radio Interferometers and Integration with the CHORD Telescope Correlators
Wellington Avelino, Joshua Montgomery, Jean-Francois Cliche +2
Wide-band correlators for radio astronomy interferometers demand accurate, scalable signal processing backends that sustain high aggregate throughput while preserving stable timing…
Unified and consistent structure growth measurements from joint ACT, SPT and \textit{Planck} CMB lensing
Frank J. Qu, Fei Ge, W. L. Kimmy Wu +143
We present the tightest cosmic microwave background (CMB) lensing constraints to date on the growth of structure by combining CMB lensing measurements from the Atacama Cosmology Te…
Readout noise of digital frequency multiplexed TES detectors for CUPID
Michel AdamiÄ, Joseph Camilleri, Chiara Capelli +10
Superconducting transition-edge sensor (TES) detectors have been the standard in Cosmic Microwave Background experiments for almost two decades and are now being adapted for use in…
In-situ control of the resonant frequency of kinetic inductance detectors with multiplexed readout
Maclean Rouble, Michel AdamiÄ, Peter S. Barry +5
Large multiplexing factors are a primary advantage of kinetic inductance detectors (KIDs), but the implementation of high density arrays still presents significant challenges. Devi…
