This paper deals with the simulation of output beam parameters inverse Compton X-ray Source (ICS). The takes into account main laser and electron beams, such as their pulse shapes, polarization properties well angular energy dispersion electrons. layout presented ICS optical beamline is dedicated to micro-diffraction studies. To maintain axial symmetry beams at different photon energies, monoch...

zno and zno:mn nanocrystals synthesized via reverse micelle method. the size, band gap, urbach energy, optical constants and penetration depth of nanocrystals were calculated by uv-vis spectroscopy data. the surface morphology was studied with the use of scanning electron microscope (sem). moreover the samples exposed to gama ray source of 60co and their thermoluminescence properties were also ...

We have examined a probable soft X-ray transient source in the M31 bulge at R.A.=0:42:41.814 ± 0.08, Dec. = 41:16:35.86 ± 0.07. On the three occasions we observed the source, its spectrum was soft (kTin ≈ 1 keV). The brightest detection of the source was 2004 July 17 with a 0.3–7 keV luminosity of ∼5×10 erg s. The only previous detection of the source was in 1979 by the Einstein observatory. Th...

The pulsar PSR J0631+1036 was discovered during a radio search of Einstein X-ray source error circles. A detection of a 288ms sinusoidal modulation in the ASCA lightcurve, the same period as the radio pulsar, appeared to confirm the association of the X-ray source and the pulsar. Its X-ray spectrum was said to be similar to that of middle aged γ-ray pulsars such as Geminga. However, an XMM-Newt...
