The design of a 31-Mev betatron to be used in fundamental research on radiology and radiation therapy is described. The head of the betatron is composed of a magnet with doughnut, constructed of a special glass with its inner surface covered with a refractory transparent semiconducting film; a lead radiation shield; a variable-field-size beam shutter; electron beam direction adjusting devices; and a diagnostic x-ray apparatus. The electrical circuits are composed of a power circuit pulse generator, an electron direction adjusting device, an initial field correction device, a holding mechanism control board, and a main control desk. The x-ray output obtainable is 140 r/min and the electron output is 3000 r/min from the rotation axis. The noise level is less than 75 phonons at 1 m from the head. Rotational therapy is possible without moving the patient during irradiation. (M.C.G.)
