1. Способ генерации мягкого (и жесткого) направленного (и изотропного) некогерентного (немонохроматического) рентгеновского излучения, отличающийся тем, что, с целью получения пикосекундных импульсов рентгеновского излучения из микрообъемов плотной плазмы вакуумно-искровых и дуговых разрядов, инициированных лазерным импульсом либо с помощью электровзрывов микропроводников, в условиях малых межэлектродных зазоров (от 100 мкм и ниже) при пониженных прикладываемых напряжениях (вплоть до 12 В) в режимах контактного коллапса при развитии микроплазменного фокуса вблизи сеточного анода (или анода имеющего сквозное отверстие, через которое могут улетать электроны и ионы, уносящие избыточную энергию).1. A method of generating soft (and hard) directed (and isotropic) incoherent (non-monochromatic) X-ray radiation, characterized in that, in order to obtain picosecond pulses of X-ray radiation from microvolumes of dense plasma of vacuum-spark and arc discharges initiated by a laser pulse or by electrical explosions of microconductors, in conditions of small interelectrode gaps (from 100 μm and below) at low applied voltages (up to 12 V) in contact collapse modes during microdevelopment a plasma focus near the grid anode (or an anode having a through hole through which electrons and ions that carry off excess energy can fly away). 2. Способ по п.1, отличающийся тем, что с целью получения когерентного (лазерного) направленного (или изотропного) рентгеновского излучения используются особо чистые вещества (материалы электродов), электровзрывной переход микрочастей которых в экстремальные состояния происходит с соблюдением условий реализации режима УСИ-усиления спонтанного излучения.2. The method according to claim 1, characterized in that in order to obtain coherent (laser) directed (or isotropic) X-ray radiation, highly pure substances (electrode materials) are used, the electro-explosive transition of which microparticles to extreme states occurs subject to the conditions for the implementation of the USI mode amplification of spontaneous emission. 3.
