The results of testing an experimental model of the 5-Mev linear electron accelerator which is intended for beta and gamma therapy are reported. The accelerating system is made in the form of a 2338.3-mm long septate waveguide operating at pi2 mode. The initial 767-mm long section of the waveguide has variable dimensions so that the phase velocity and field-strength amplitude can be continuously varied to ensure a high capture coefficient. These measured characteristics are presented energy and accelerated-beam energy-spectrum width vs. frequency maximum energy, around 2798.6 Mc ratio of accelerated-particle current to injection current capture vs. frequency 80 corresponds to about 2800 Mc energy, energy-spectrum width and capture vs. r-f power same quantities vs. injection current energy and energy-spectrum width vs. injection current energy and energy-spectrum width vs. injection voltage. The energy spread of electrons at the spectrum half-height is plus or minus 5 or less the average current of accelerated electrons, 70 micro a.
