Book Description
Two-dimensional discrete ordinates calculations have been performed to determine the location and thickness of concrete shielding around the Tokamak Fusion Test Reactor (TFTR) neutral beam injectors. Two sets of calculations were performed: one to determine the dose equivalent rate on the roof and walls of the test cell building when no injectors are present, and one to determine the contribution to the dose equivalent rate at these locations from radiation streaming through the injection duct. Shielding the side and rear of the neutral beam injector with 0.305 and 0.61 m of concrete, respectively, and lining the inside of the test cell wall with an additional layer of concrete having a thickness of 0.305 m and a height above the axis of deuteron injection of 3.10 m are sufficient to maintain the biological dose equivalent rate outside the test cell to approx. 1 mrem/DT pulse.

Book Description
Estimates, based entirely on one-dimensional transport calculations, of some of the effects of radiation on the operation and maintenance of the neutral beam injector for the Tokamak Fusion Test Reactor (TFTR) to be built at the Plasma Physics Laboratory of Princeton University are presented. Radiation effects due to 14-MeV neutrons produced by D-T reactions in the plasma and due to 2.6-MeV neutrons produced by D-D reactions in the calorimeter and in the charged-deuteron beam dump are considered. The results presented here are intended to indicate potential radiation problems rather than to be an accurate estimate of the magnitude of the actual radiation effects that will exist in the vicinity of the final injectors.

Book Description
The initial rate of rise of the central electron density during (approximately)100 keV deuterium neutral beam injection is found to agree well with calculations of the beam deposition rate. The best agreement is with beam deposition calculations using older tabulations of the atomic cross-sections; the effects of using new tabulations or including multi-step ionization processes appear to approximately cancel. The neutral-beam deposition profile is a strong function of both the magnitude and the shape of the target plasma density. Peaked heating profiles can be achieved at high target densities only from peaked target density profiles. 15 refs., 4 figs.
