The design of neutral beam injection systems for PLT provided adequate heating of the device plasma. This design with some minor modification was used on ISX. In order to achieve injection of MW from each neutral beam system for PDX and ISX-B, major changes in the base line design were required in a number of mechanical systems. The paper describes these changes along with modification for Author: R. L. Johnson, W. L. Gardner, R. A. Michelotti, J. R. Moore, T. L. Ryan, J. E. Warwick, H. C. McCurd. Two PLT‐injector‐type duoPIGatron sources, modified further by shaping the beam‐forming apertures, have been tested and experimented on a protype beam line similar to the ISX‐B neutral beam injection system. The accelerator column modification has resulted in an increase of the beam power transmission efficiency from that of the straight‐bore aperture by 50%.Cited by: Topics: Ion Sources, Beam Injection, Cryopumps, Testing, Plt Devices, Laboratory Equipment, 70 Plasma Physics And Fusion Technology, Neutral Beam Sources, Performance Testing, Penning Ion Sources, Efficiency, Neutral Atom Beam Injection, Thermonuclear Devices, Pumps, Vacuum Pumps * -- Fusion Power Plant Technology-- Fuel, Heating, & Injection Systems, Closed Plasma .

ORNL/PLT Neutral Beam Injection Systems, Major Project Proposal, ORNL/TM (). R. C.   1. Introduction. The Large Helical Device (LHD) has been designed with a negative ion-based neutral beam injection (NBI) system of energetic hydrogen atoms as the main heating system,.Its purpose is to deliver an injection power of 15 MW with a beam energy of keV for 10 s, and a quasi-steady injection for 30 min. with a reduced power of 3 MW. The injection of fast neutral beams has been used as a plasma heating tool on the PLT tokamak for approximately two years. The first injector was installed in the summer of and the fourth in the spring of The heating experiments have yielded favorable results, with a maximum D(degree) beam power injected so far of MW, driving the central ion temperature to keV, at a mean. Neutral beam injection (NBI) is one method used to heat plasma inside a fusion device consisting in a beam of high-energy neutral particles that can enter the magnetic confinement field. When these neutral particles are ionized by collision with the plasma particles, they are kept in the plasma by the confining magnetic field, and can transfer most of their energy by further collisions with.

The theory was applied to carry out a detailed analysis of the large experimental database from the PLT and the ISX-B tokamaks. The theory was found to generally model the experimental data quite well. It is, therefore, concluded that neutral beam co-injection can drive impurities outward to achieve clean central plasmas and a cool radiating edge. The PDX Neutral Beam Injection System consists of four beamlines of basic PLT injector design with changes primarily related to the containment of increased beam power and pulse length.
