Double photon excitation of high-Rydberg atoms as a long-lived submillimeter detector [PDF]

, 1986
A method and apparatus for detecting submillimeter or IR radiation is disclosed. A rare gas, such as xenon, is supplied at its ground state via a pressurized cylinder and an adjustable leak valve into a cryogenically cooled detection area.

Geometric phase shift for detection of gravitational radiation

, 2004
An effect of geometrical phase shift is predicted for a light beam propagating in the field of a gravitational wave. Gravitational radiation detection experiments are proposed using this new effect, the corresponding estimates being given.Comment ...

Semiconductor materials and radiation detection [PDF]

Journal of Synchrotron Radiation, 2006
While Si and Ge have become detection standards for X-ray and gamma-ray spectroscopy in the laboratory, their use for an increasing range of applications is becoming marginalized by one or more of their physical limitations; namely the need for ancillary cooling systems or bulky cryogenics, their modest stopping powers and radiation intolerance.

Astrobiological Effects of F, G, K and M Main-Sequence Stars

, 2008
We focus on the astrobiological effects of photospheric radiation produced by main-sequence stars of spectral types F, G, K, and M. The photospheric radiation is represented by using realistic spectra, taking into account millions or hundred of millions ...
