主　　题：Fast ions 

摘      要：A code that models signals produced by charge-exchange reactions between fast ions and injected neutral beams in tokamak plasmas is *** the fastion distribution function as input,the code predicts the efflux to a neutral particle analyzer(NPA)diagnostic and the photon radiance of Balmer-alpha light to a fastion Dα(FIDA)*** with both the primary injected neutrals and with the cloud of secondaryhaloneutrals that surround the beam are *** calculation of the fraction of neutrals that occupy excited atomic states(the collisionalradiative transition equations)is an important element of the *** with TRANSP output and other tests verify the *** selection of grid size and other parameters facilitate efficient *** output of the code has been validated by FIDA measurements on DIII-D but further tests are warranted.
