Abstract :

The extreme operating mode of a �??table-top�?� (diameter 120 mm, length 350 mm) high-voltage (U = 280 keV) high-current (I = 5 kA) electron accelerator with a beam duration of 200 ps is investigated. The luminescent method shows that the beam diameter in the uniform pinching mode is about a micrometer, and the beam contains electrons with an energy exceeding 400 keV, which are about 1/4 of the total number of electrons in the beam. Result of the analysis of the bremsstrahlung X-ray spectrum of the beam electrons is consistent with this data with satisfactory accuracy. Also, it is established that the ions of the cathode material Tin+ captured by the electron beam are accelerated up to an energy of �?� 10 MeV, and the ion fluence reaches 1017 ion cm-2 in the pulse. These ions are effectively embedded into the lattice sites of the irradiated substrate (sapphire crystal), forming the luminescent areas of the micron scale
