Abstract :
An electron-optical system with a thermionic cathode allowing production of a 0.6 mm diameter thin rectilinear electron beam with an energy of 250 keV, current of 15 A and pulse duration of 10 μs in an axial magnetic field of 16 kG is designed and constructed. A pumping system transforms the straight beam into a beam of electrons gyrating around the axis with a velocity ratio of 1.5 and sufficiently small velocity spread. Results of numerical simulations and experiments are presented. The obtained beam will be used for cyclotron resonance maser experiments
