Addressing Individual Persistent Current Switches With a Cryogenic Optical Scanner

March 6, 2026

Author(s)

Avirup Roy, Jonathan Dean, Galen O'Neil, Nathan Ortiz, Paul Szypryt

We demonstrate a robust and minimalist implementation of individually addressable optically actuated persistent current switches. We use a focused laser beam directed by a cryogenic laser scanner to drive a selected segment of a superconducting loop normal

Characterization of Silicon-Membrane TES Microcalorimeters for Large-Format X-ray Spectrometers with Integrated Microwave SQUID Readout

January 16, 2026

Author(s)

Avirup Roy, Robinjeet Singh, Joel Weber, William Doriese, Johnathon Gard, Mark Keller, John Mates, Kelsey Morgan, Galen O'Neil, Nathan Ortiz, Daniel Swetz, Daniel Schmidt, Joel Ullom, Evan Jahrman, Thomas Allison, Sasawat Jamnuch, John Vinson, Charles Titus, Cherno Jaye, Daniel Fischer

We present the electrothermal characterization of transition-edge sensor (TES) detectors suspended on Si membranes fabricated using a silicon-on-insulator wafer. The use of an all-silicon fabrication platform, in contrast to the more commonly used silicon
