A linear electron accelerator with a travelling wave of 3.5 Mev energy is described. A waveguide loaded with disks is used as accelerating system. The necessary law of wave phase velocity variation is brought about by variation of the diameter of the apertures in the disks. The 280-cm long waveguide is divided into three sections. In the first section, the phaee velocity is varied from 0.5 to 0.97 c; in the second and third sections it is equal to 0.98 and 0.99 c, respectively. The electron equilibrium phase increases during the acceleration process; its initial value is equal to 45 deg and is chosen according to the optimum capture condition. The computational value of the hf power at the accelerator input is 900 kw; the accelerator field intensity amounts hereat to 16.5 kv/cm. The accelerator output power (sbout 600 kw) is absorbed in a steel load with water ccoling; approximately 300 kw are dissipated in the waveguide walls. An additional axisymmetrical magnetic field with an intensity up to 400 gauss is developed by solenoids for focusing the electrons along the waveguide axis. An electron gun with three electrodes serves as electron source; it operates pulsing synchronously with the magnetron generator and provides for beam of 5 to 6 mm diameter at the accelerator input. The output parameters of the accelerator measured are: the current is about 20 to 30 ma in the pulse of 2 mu sec duration, the average current is about 20 to 30 mu a; the beam diameter is 3 to 4 mm with the divergence angle of 7 x 10/sup -//sup 4/ to 3 x 10/sup -//sup 3/ radian; the energy beam half-width is about 8%.
