A seminar by Aleksey Bogomolov on “Development of the Backward Wave Linear Accelerator of Protons (Project BWLAP) with megawatt beam power and applicability in the high-flux neutron generator” will be held in the Conference hall of Frank Laboratory of Neutron Physics JINR on 16 November 2017. Aleksey Bogomolov is the author and developer of the backward wave linear accelerator technology BWALP.
In the report there are considered peculiarities and advantages of the acceleration method of backward spatial harmonic, the high-frequency power propagating against the flow of the accelerated particles and a version of developing high-current (BWLAP) proton accelerator with W=70MeV and average power Pbeam = 10 MW that may be of interest for the realization of beam focused high-flux source of neutrons.
In the 1980s of the past century a group of Soviet researchers headed by Aleksey Sergeevich Bogomolov developed the acceleration technology of positively charged particles (protons, deuterons) on the backward wave – BWLAP. The key point of this technology is the acceleration of elementary particles by the electrical component of the electromagnetic field, shifting to the same direction and with the same accelerated speed as accelerated ions. In this respect, the source of electromagnetic waves is installed at the end of the accelerator opposite the injected, and the wave propagates against the energy flux – thereby the wave (spatial harmonic) is inverse (directed oppositely) towards the direction of the energy flux.
The acceleration method on the inverse spatial harmonic allows:
- To solve the problem of the pitching and transverse stability of the accelerated protons;
- To implement 95% capture of the injected by the flux in the proton beam accelerator at the rate of stable acceleration;
- To increase in 10 times the frequency of the accelerated proton in the high-frequency electromagnetic field and to implement the acceleration in the decimeter wavelength range.
