Abstract
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 γ-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 γ-pulse is 120 ns, and the dimensions of the radiation source are 3 \( \times \) 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.
