Superconducting tunnel junctions can be used as part of a high-resolution, energy-dispersive x- ray detector. The energy of the absorbed x ray is used to break superconducting electron pairs, producing on the order of 106 excitations, called quasipar

Superconducting tunnel junctions have the potential to serve as high-resolution, high-efficiency x-ray detectors for astrophysical and industrial applications. When irradiated by X rays, each X ray excites over 106 charge carriers which cause the det

We are developing superconducting tunnel junction devices for use as high-resolution, high- efficiency x-ray spectrometers. We have tested devices with niobium x-ray absorbing layers coupled to aluminum layers which serve as quasiparticle traps. Thes

A multichip silicon-on-silicon packaging technology has been developed which incorporates laser-patterned thin-film interconnects. This technology is particularly suited for application in high-speed, high-power, and high-I/O systems, where its uniqu

Two‐pulse techniques using high power lasers have been developed for the study of collisional deactivation of vibrationally excited molecular ions in the gas phase. Using these techniques, absolute rate constants have been determined for quenching

Major advances have been made in the measurement and analysis of gas phase ionic organic reactions. The dynamics can be interpreted in terms of statistical reaction rate theory. The activation parameters and rates have been interpreted in terms of Ma
