Neutral beam injection is a standard method to heat the plasma in fusion experiments also has important diagnostic uses. Modelling of beam penetration into the plasma and of photoemission signals relies on detailed data for atomic processes. There are quite significant gaps in these data and the data that are available are often of uncertain quality.
This CRP will provide evaluated and recommended data for the principal atomic processes relevant to heating and diagnostic neutral beams in fusion plasmas. The primary emphasis is on processes of hydrogen (H, D, T) neutral beams in the high temperature core plasma.
Two code comparison workshops are planned in conjunction with this CRP:
