Abstract:
A high energy photon source comprising:A. a vacuum chamber, B. two electrodes located within said vacuum chamber and defining an electrical discharge region between said two electrodes and arranged to create high frequency plasma pinches focused at a pinch site outside said electrical discharge region upon electrical discharge, C. a working gas comprising an active gas and a buffer gas, said buffer gas being a noble gas, and said active gas being chosen to provide light at least one spectral line, D. a working gas supply system for supplying a working gas to said discharge region, E. a pulse power source for providing electrical pulses and voltages high enough to create electrical discharge between said at least one pair of electrode, F. an external reflection radiation collector-director for collecting radiation produced in said plasma pinches and for directing said radiation in a desired direction, and G. a conical nested debris collector having at least five conical surfaces aligned with light rays extending out from the pinch site toward the radiation collector-director; wherein at least four of said at least five conical surfaces are nested within one of said five conical surfaces.
