Abstract

A neutral beam injection heating simulation of time-development plasma in the Large Helical Device high-ion-temperature experiment is presented. The effects of the time-development of density and temperature on the beam ion birth profile and slowing-down are considered using a new code, GNET-TD, which is based on GNET. The simulation results show that heat deposition to ions increases in the core region when the density decays after pellet injection.
