TANDEM VAN DE GRAAFF ACCELERATOR, 12 Mev (Engineering Materials)

OSTI ID:4674644

This package contains 20 drawings. The 12-Mev Tanden Van de Graaff accelerator was completed in 1962. Proton beams of various energies up to 12 Mev; nitrogen-- ion beams of 30 Mev; and oxygen--ion beams as high as 42 Mev were produced. Energy resolution of these beams was better than 0.1%. These higher- energy beams were made possible by the charge-exchange'' mechanism employed to achieve double acceleration. Singly charged negative ions were injected and accelerated to the positive terminal of the accelerator where they encountered a higher-density oxygen gas region. The high velocity negative ions lost electrons to neutral gas molecules and became positive ions which were further accelerated from the terminal to the ground potential. Included are the following auxiliaries used with the tandem Van de Graaff Accelerator: cable trough for rack cabinets; hatchway plaiform; magnet leveling device; analyzing magnet chambers, 28 1/2 in. and 34 in. in radii; actuator drive unit; pneumatic beamviewer cup; and a faraday beam cup for the actuator.
