原始语种摘要: We discuss α -particle velocity-space diagnostic in ITER based on the planned collective Thomson scattering (CTS) and γ -ray spectrometry (GRS) systems as well as ASCOT simulations of the α -particle distribution function. GRS is sensitive to α -particles with energies MeV at all pitches p , and CTS for MeV and . The remaining velocity space is not observed. GRS and CTS view the plasma (almost) perpendicularly to the magnetic field. Hence we cannot determine the sign of the pitch of the α -particles and cannot distinguish co- and counter-going α -particles with the currently planned α -particle diagnostics. Therefore we can only infer the sign-insensitive 2D distribution function by velocity-space tomography for MeV. This is a serious limitation, since co- and counter-going α -particle...
