Title: BEAM-PROFILE INDICATOR FOR 184-INCH CYCLOTRON (thesis)

Abstract

A closed-circuit television chain was constructed and evaluated as a monitor for the external charged-particle beam of the 184-inch cyclotron. A sheet of plastic scintillator placed in the beam gave off light which was picked up by the camera and transmitted to the remote counting area for direct display. Magnetic shielding of the camera's deflection and focusing components was necessary for operation in the cyclotron fringing field. A light-tight enclosure for the scinitillator and camera lens permitted the image orthicon to be adjusted for a light sensitivity not attainable in high ambient light levels. A beam of lO/sup 7/ protons dispersed over an area of approximately 4 cm/sup 2/ was adequately monitored with this equipment. Beams of 105 particles over the same area should be discernible when the system is optimized. (auth)
