    摘要: A light source device that irradiates a discharge vessel with a laser beam to produce radiant light that is reflected by an ellipsoidal reflecting surface efficiently utilizes the light produced by directing the laser beam through an unirradiated region where reflected light from the ellipsoidal reflector is blocked by the discharge vessel, through an opening side of the ellipsoidal reflector to the discharge vessel. The discharge vessel has an emission substance enclosed inside which is excited by the laser beam and produces radiant light, is arranged at a focal point of the ellipsoidal reflector. A planar mirror, with which radiant light reflected by the ellipsoidal reflector is reflected in a different direction has a window in an unirradiated region where reflected light from the ellipsoidal reflector is blocked by the discharge vessel through which the laser beam passes to the discharge vessel.

    摘要: This invention teaches a method of performing gamma-ray microscopy and how to build a gamma-ray microscope. While the beam of gamma rays can not be manipulated like a beam of light or a beam of electrons, magnification is possible using a single-point source of gamma radiation. With this design, gamma rays originate from a tiny point in space and radiate outward as they travel away from the source. This results in magnification when a sample is placed between this single-point source and a detector array. The magnification factor is equal to the source-to-detector distance divided by the source-to-sample distance. A single-point source of gamma rays can be made by crossing a beam of positrons with a beam of electrons. The finer and more focused these beams are, the smaller the single-point source can be, and the higher the resolution can be. Methods of making and focusing electron beams are known in the art of making electron microscopy. These methods can be adapted to accelerate and focus positrons into a fine beam. Positrons can be harvested from radioactive isotopes that emit positrons and trapped by electric fields and magnetic fields for use when necessary. Mini versions of particle accelerator can trap positrons in an orbit for regulated or pulsed beam of positrons to be generated.

    摘要: The invention provides targets coated with structured biological materials, which are employed in laser produced plasma systems. The biological materials selected from cells of microbial, protozoan or plankton origin are applied on a portion of a solid target, like polished glass plate which then form a target system that absorbs the intense laser pulses, generates hot dense plasma and results in the emission of the X-rays. The method of coating structured biomaterial decreases the usable laser intensity required for producing the hot plasma, while increasing the X-ray yield. The coatings are easy to prepare and it is possible to vary the nature and shape of the cellular material in order to control/regulate the interaction with the light and thereby optimize the resultant plasma generation and X-ray emission. The increase in temperature of the plasma and the increase in yield demonstrate that the method is suitable for enhancing the emission yield in the Ultra Violet, Extreme Ultra violet, x-ray and the hard x-ray regimes.
