Hard Polarized Photon Emission in Single Crystals by High Energy Electrons for Planar Crystal Orientations
The radiation emission spectra of polarized photons emitted from charge
particle in single crystal are obtained in semiclassical theory in
Baer-Katkov-Strakhovenko approximation for planar crystal orientation. The
range of applicability of this approximation is estimated by comparing the
results with calculations in exact semiclassical theory. Optimal crystal
orientations for producing unpolarized and polarized photon beams are also
founded.Comment: 10 pages, 5 figures, (wpapfig,epsfig
Background Thermal Contributions in Testing the Unruh Effect
We consider inertial and accelerated Unruh-DeWitt detectors moving in a
background thermal bath and calculate their excitation rates. It is shown that
for fast moving detectors such a thermal bath does not affect substantially the
excitation probability. Our results are discussed in connection with a possible
proposal of testing the Unruh effect in high energy particle accelerators.Comment: 13 pages, (REVTEX 3.0), 3 figures available upon reques
