“…These investigations allowed us to significantly increase the proton beam current. In the initial experiments the characteristic value of the current was 100 -200 μA [13,14], but now we obtain more than 1 mA in a long steady mode. Figure 4 shows the time dependence of the ion beam current measured at the output of the accelerator.…”

New type of charged particles accelerator, tandem accelerator with vacuum insulation, was proposed in BINP. The accelerator is characterized by fast acceleration of charged particles, long distance between ion beam and insulator (on which electrodes are mounted), big stored energy in the accelerating gaps and strong input electrostatic lens. High-voltage strength of vacuum gaps, dark currents, ion beam focusing, accelerating and stripping were investigated. Stationary proton beam with 2 MeV energy, 1.6 mA current has just been obtained. The beam is characterized by high-energy monochromaticity-0.1%, and high current stability-0.5%. Here we report the results of these investigations and discuss the proposal for obtaining 2.5 MeV 3 mA proton beam. The accelerator is considered to be a part of epithermal neutron source for boron neutron capture therapy and monoenergetic neutron source for calibration of dark matter detector.

“…It was measured by two ways. The first way used generation of 9.17 MeV gamma rays from the reaction 13 C(p,γ) 14 N, when the proton beam with energy higher than 1.747 MeV irradiated a graphite target enriched with the carbon-13 isotope. BGO-spectrometer was used to measure the count rate of gamma rays depending on proton energy.…”

A compact accelerator-based neutron source has been proposed and created at the Budker Institute of Nuclear Physics in Novosibirsk, Russia. An original design tandem accelerator is used to provide a proton beam. The proton beam energy can be varied within a range of 0.6–2.3 MeV, keeping a high-energy stability of 0.1%. The beam current can also be varied in a wide range (from 0.3 mA to 10 mA) with high current stability (0.4%). In the device, neutron flux is generated as a result of the 7Li(p,n)7Be threshold reaction. A beam-shaping assembly is applied to convert this flux into a beam of epithermal neutrons with characteristics suitable for BNCT. A lot of scientific research has been carried out at the facility, including the study of blistering and its effect on the neutron yield. The BNCT technique is being tested in in vitro and in vivo studies, and the methods of dosimetry are being developed. It is planned to certify the neutron source next year and conduct clinical trials on it. The neutron source served as a prototype for a facility created for a clinic in Xiamen (China).
