The wake field of an electron bunch moving parallel to the axis of a dielectric cylinder is being considered. It is shown that for a relativistic bunch (gamma>>1) the circular harmonic of order zero contributes a decelerating force inversely proportional to gamma, whereas the circular harmonics of nonzero order contribute a gamma-independent force. Moreover, the wake linked to the circular harm...
The Gamma-Ray Large Area Space Telescope (GLAST), scheduled to be launched in Fall 2007, is a next generation high energy gamma-ray observatory. The Large Area Telescope (LAT) instrument on-board GLAST with a wide field of view (> 2 sr), large effective area and 20 MeV to >300 GeV energy range, will provide excellent opportunity for future Dark Matter studies. We present an overview of the GLAS...
We use K(L)'s in the 100-200 GeV energy range to produce 147 candidate events of the axial vector pair K1(1270)-K1(1400) in the nuclear Coulomb field of a Pb target and determine the radiative widths Gamma(K1(1400)-->K0+gamma)=280.8+/-23.2(stat)+/-40.4(syst) keV and Gamma(K1(1270)-->K0+gamma)=73.2+/-6.1(stat)+/-28.3(syst) keV. These first measurements appear to be lower than the quark-model pre...
A brief survey of plastic scintillators for various radiation measurement applications is presented here. The utility of plastic scintillators for practical applications such as gamma radiation monitoring, real-time radioisotope detection and screening is evaluated in laboratory and field measurements. This study also reports results of Monte Carlo-type predictive responses of common plastic sc...
Pool-type reactors are an excellent source of high energy photons without neutrons because the water above fuel acts as outstanding neutron shielding, whereas for photons, it is nearly transparent. The absence a valuable property essential testing semiconductor detectors they sensitive to neutrons, which might cause their damage. gammas worth studying responsible radiation induced heating react...
