Development of laser driven high-brightness fast x-ray sources is a key application of the PHELIX laser for experiments in combination with the heavy ion accelerator. X-ray diagnostics of high-energy density states of matter produced with intense heavy ion beams from GSI or FAIR will require multi-keV x-ray energies to penetrate the dense plasma [1]. Recent development of backlighter sources at...

in this research work, alpha particle detector is made using semi-insulating gaas. a surface barrier detector with a semi-insulating gaas substrate at room temperature with pressure of 10-4 torr under -particle radiation with 5.48 mev of am241 source, have been under investigation. energy resolution of 2 and 3 mm schottky diameter have been matured and compared with the effect of voltage varia...

Formation of 7 alpha-hydroxycholesterol by rat liver microsomes was quantitated using a gas chromatograph-mass spectrometer operated in selected ion monitoring mode. This procedure measures the mass of 7 alpha-hydroxycholesterol formed and does not require addition of labeled cholesterol to monitor the reaction, since endogenous microsomal cholesterol serves as substrate for the enzyme choleste...

The extremely small probability of quantum tunneling through an almost classical potential barrier may become not small under the action of the specially adapted nonstationary field. The tunneling rate has a sharp peak as a function of the particle energy when it is close to the certain resonant value defined by the nonstationary field (Euclidean resonance). Alpha decay of nuclei has a small pr...

[1] Neutral particle dominance over charged particles in Saturn’s magnetosphere was evident prior to Cassini’s arrival at Saturn in 2004. The observation of active plumes emanating from the south pole of Enceladus suggests that this small moon is likely to be the principal source of neutrals in Saturn’s magnetosphere. Cassini has flown through the plumes on several occasions, and the resulting ...

In this work, the influence of Magnolol on the bystander effect in alpha-particle irradiated Chinese hamster ovary (CHO) cells was examined. The bystander effect was studied through medium transfer experiments. Cytokinesis-block micronucleus (CBMN) assay was performed to quantify the chromosome damage induced by alpha-particle irradiation. Our results showed that the alpha-particle induced micr...

The HEAT (High Energy Antimatter Telescope) instrument was successfully own by high altitude balloon in May 1994. HEAT combines a new magnet spectrometer, comprised of a two-coil superconducting magnet and precision drift tube hodoscope, with a transition radiation detector and electromagnetic shower counter for particle identiication. Flight data are presented which demonstrate that the spectr...
