- Summary:
- A TFTR supershot with a plasma current of 2.5 MA, neutral beam heating power of 33.7 MW, and a peak DT fusion power of 7.5 MW is studied using the TRANSP plasma analysis code. Simulations of alpha parameters such as the alpha heating, pressure, and distributions in energy and v{sub parallel}/v are given. The effects of toroidal ripple and mixing of the fast alpha particles during the sawteeth observed after the neutral beam injection phase are modeled. The distributions of alpha particles on the outer midplane are peaked near forward and backward v{sub parallel}/v. Ripple losses deplete the distributions in the vicinity of v{sub parallel}/v ∼−0.4. Sawtooth mixing of fast alpha particles is computed to reduce their central density and broaden their width in energy.
