We characterize the operation of large-area high-gain silicon avalanche photodiodes (APDs) at near liquid-nitrogen temperatures. The APDs that we studied have active areas of 64 mm2 and have gains of up to 20 000 at 85 K. We characterized the devices

We have developed an atomic beam technique for studying magnetic vortices and vortex lattices of superconductors. Atoms moving near a superconductor`s surface see a fluctuating magnetic field as they pass vortices. This field may drive magnetic reson

We describe our work on gold surfaces that are made by peeling gold films off various smooth glass substrates. We find that we are able to routinely and reliably produce extremely smooth, large area gold surfaces: typically, for areas ≤40 μm squar

We report measurements of the low-field structure of the magnetic vortex lattice in an untwinned YBCO single-crystal platelet. Measurements were carried out using an atomic beam magnetic-resonance (ABMR) technique. For a 10.7 G field applied parallel

We have detected single 650 nm photons with quantum efficiencies greater than 60% using a large area silicon avalanche photodiode. We cool a 5 mm diam commercially available device to 100 K and operate in the gain‐mode. For most applications—from

We report the homodyne detection of phase modulation sidebands induced on a laser beam by a coherently bunched electron beam. This provides a sensitive and nonperturbing measurement of complex Fourier time series components of the electron density. A

We have developed an atomic beam technique for studying the Abrikosov vortex lattice. Atoms skimming the surface of a superconductor in the intermediate state experience a temporally fluctuating magnetic field due to the spatial variation of the loca
