Feasibility of alpha‐particle measurement by CO2 laser Thomson scattering

摘要: The feasibility of CO2 laser Thomson scattering from a multicomponent burning plasma has been evaluated for the measurement velocity distribution D–T‐produced alpha particles. density and particles their initial energy 3.5 MeV down to near‐thermal energies may be measured by small‐angle (<1°) scattering. A computer simulation experiment indicates that 100‐MW pulsed combined with bank heterodyne receivers will able measure scattered signal postdetection signal‐to‐noise ratio 75 an assumed 7.5×1011 cm−3.
