摘要：

A mobile accelerator based on an ironless pulsed betatron is presented. The accelerator is designed for radiography of dynamic objects with large optical thicknesses and allows generation of up to three gamma-pulses per acceleration cycle. Operation of the accelerator is described, and the results of test runs in the single-pulse mode are given. The estimated cutoff energy of the electron beam is 60 MeV at a storage capacity of 1.8 mF of the pulsed power supply system of the betatron electromagnet. The thickness of a transilluminated lead test object is 140 mm at a distance of 4 m from the radiation source (betatron target), the FWHM of the output gamma-pulse is 120 ns, and the dimensions of the radiation source are 3 6 mm. Application of such accelerators in X-ray complexes will make it possible to optimize the scheme of gas-dynamic experiments, reduce the cost of the latter and, hence, increase the efficiency of research.
