A superconducting NbN detector for neutral nanoparticles.
We present a proof-of-principle study of superconducting single photon detectors (SSPD) for the detection of individual neutral molecules/nanoparticles at low energies. The new detector is applied to characterize a laser desorption source for biomolecules and allows retrieval of the arrival time distribution of a pulsed molecular beam containing the amino acid tryptophan, the polypeptide gramic...

We IHC'senl spatially re.l:lotved st.udies of vortex dynalnics in two-diInclIsional Joscphson-jullctioll arrays For bias currents smaller than the array critical current, a small local thermal perturbation at the array boundaries lowers the vortex entry barrier and the array switches to the resistive state. For bias currents slightly above the array critical furrent., vortices and antiyortices ...
متن کاملPhotonic Materials and Devices
Our recent advances in solid-state optoelectronic materials and devices will be reviewed. In the area of glass optics, fabrication of novel microstructured and multi-core fibers and their use in realizing single mode lasers will be summarized. In organic and plastic optics, photorefractive polymers for 3D display applications and nonlinear optical polymers for high speed modulators in RF photon...
متن کاملSuperconducting Materials for Magnets
Superconducting materials for magnets will be discussed from three viewpoints: firstly the basic physical properties of the materials themselves, secondly the constraints and preferences imposed by the requirements of magnet building and finally, the manufacture of magnet conductors as a commercial product.
متن کاملNegative Resistance Effects in NbN HEB Devices
It is well known that HEB devices, whether phonon-cooled or diffusioncooled, exhibit unstable regions of their IV-characteristics. These phenomena occur when the device is not pumped by the LO, or when the LO power is decreased sufficiently compared with the power level required for optimum operation. The bias voltage is between the critical value at which the device stops being superconducting...
