摘要: A TFTR supershot with a plasma current of 2.5 MA, neutral beam heating power 33.7 MW and peak DT fusion 7.5 is studied using the TRANSP analysis code. Simulations alpha parameters such as heating, pressure distributions in energy v1/v are given. The effects toroidal ripple mixing fast particles during sawteeth observed after injection phase modelled. on outer midplane peaked near forward backward v1/v. Ripple losses deplete vicinity v1/v=-0.2. Sawtooth computed to reduce their central density broaden width
