Calculation of high-current linear proton accelerator with an energy of 80 MeV

This article considers the possibility of pulsed acceleration in a spiral waveguide of a proton beam with the current I_b = 0,7 A. The accelerator consists of three parts. The energy of the proton injection is 50 keV. In the first part of the accelerator having the length L_acc1 ≈ 1.4 m, the protons are accelerated up to the energy ϵ_1fin = 0.8 MeV. In this section of the accelerator, consumption of high-frequency power is P₁ = 0.8 MW. In the second part of the accelerator with the length L_acc2 ≈ 2 m, the protons are accelerated up to the energy ϵ_2fin = 5 MeV. Consumption of high-frequency power in the second part of the accelerator is P₂ = 4 MW. The third part of the accelerator consists of 8 sections, each being 7 m long. Radial focusing of the proton beam in this accelerator is carried out with the magnetic field intensity H = 10 , generated by a superconducting solenoid.
