“…It is known that FVIs of submicrosecond accelerators [7,8,11] operate either with forced resistive voltage distribution between sections, or are conically shaped to use capacitive distribution [18], which provided an average strength along the dielectric surface of ~25 kV/cm, while the inner diameter of the dielectric was ~350 mm. Relatively small pulse repetition rates on these highcurrent accelerators did not allow the breakdown in the low-pressure gas to develop between the cone cathode holder (also performing the function of capacitive voltage distribution) and the first sections of the FVI, as found in [18].…”

The purpose of this work was to investigate the operation of the URT-1M accelerator with a power system without SOS switch. The approaches used in the high-voltage pulse generation system of this accelerator allow generating a pulse with an amplitude of up to 500 kV, a duration of ~450 ns and a supply repetition rate up to 50 pps during discharge of the second circuit capacitor. It was found that in this mode, an accelerator with a metal dielectric cathode works stably at a charging voltage of up to 35kV (accelerating ~350 kV). Further increase of voltage is limited by breakdown of feedthrough vacuum insulator with shielding of dielectric surface.

“…In this paper, the electrical characteristics are simulated for a series of repetitive submicrosecond accelerators [9] based on a pulsed transformer [10]. This design of the accelerator uses pulsed charging of a high-voltage capacitive storage, which is switched by a commercially available pseudo-spark switch to a pulsed step-up transformer loaded directly onto a vacuum electron diode.…”

The development of complex systems computational models makes possible the evaluation of their various operation mods with minimal time and resources investment. Including the determination of the system operating parameters ranges, in which their characteristics correspond to the desired ones. This paper presents a submicrosecond electron accelerator computation made in the Multisim electrical process simulation program. The simulated accelerator is based on a high-voltage pulse generator according to the scheme of a high-voltage energy storage device, a pulse transformer, and a vacuum electron diode with an explosive emission cathode. The paper describes the applied methods and approaches of simulation development, the limitations and simplifications used, as well as the simulation error estimation. Based on the created computation, the output electrical parameters of the accelerator were analyzed depending on the amount of stored energy and the parameters of the diode system. The obtained research results can be used in the development of new exemplars of high-voltage pulse technology and for tuning existing accelerators.

“…Absorbed dose depth distribution is widely studied for monoenergetic beams [7], and there should not be any issues in measuring the depth distribution of absorbed dose at known values of the current and beam energy. However, when studying the composite-spectrum beams that are generated with compact electron accelerators based on pulsed transformer [8], it is crucial to apply such complex equipment and operose methods as the cut-off foil method, spectrometry [9], and others. Nevertheless, the problem could be simply and cheaply managed if the absorbed dose is estimated by the average electron kinetic energy value that can be measured by ratio from calorimeter data -that is a beam energy -and Faraday cups data -that is an amount of electrons.…”

Abstract. Development stages of sectioned calorimeter system combined with a detector of total electron beam current by Faraday cup for estimating charge and energy distribution of pulsed electron beam are presented. The device design was determined taking into account its use for estimating the parameters of electron beams generated by submicrosecond pulsed accelerators (up to 700 keV, 0.2–10 kA, up to 60 ns at FWHM, 0.05–10 J/cm2).
