Using a thermal sample of laser-cooled rubidium atoms, we have constructed a neutral-atom circuit analogous to an electronic capacitor discharged through a resistor. The atoms are confined using what we call a free-space atom chip, an optical dipole trap created using a generalized phase-contrast imaging technique. We have also calculated theoretical values for the capacitance and resistance, w...

Kinetic inductances of superconducting nanostrips with a meander pattern are theoretically investigated based on the London model, and effect current crowding at turns is considered. The complex approach developed for analytical investigation kinetic inductance thin $d<\lambda$ narrow $w\ll \lambda^2/d$ strips, where $d$ strip thickness, $w$ width, $\lambda$ penetration depth. We show that dist...

Design and characterization measurements performed on kinetic inductance detectors (KIDs) produced sapphire polycrystalline diamond substrates are presented. Designed as part of a nuclear fusion polarimetric diagnostic, the foreseen plasma‐probing frequency final devices is 1.3 THz with maximum response time under 10 ms cross‐polarization target accuracy 1%. These based superconducting micro‐re...

Real-time, 3D localization of the prostate for intensity-modulated radiotherapy can be accomplished with passively charged radio frequency transmitters and superconducting quantum interference device (SQUID) magnetometers. The overall system design consists of an external dipole antenna as a power source for charging a microchip implant transmitter and SQUID magnetometers for signal detection. ...
