Ion energy analyzer for measurement of ion turbulent transport
Abstract:
For local measurement of radial ion thermal transport, we developed a novel time-resolved gridded ion energy analyzer. The turbulent thermal flux is obtained by correlating fluctuations of ion temperature, plasma density and plasma velocity. The simultaneous measurement of the ion current fluctuations from an ion energy analyzer Ĩ(IEA)(t) and the fluctuation of ion saturation current from a conventional Langmuir probe Ĩ(LP)(t) allow us to determine local fluctuations of ion temperature T(i)(t). To reduce the effect of plasma potential fluctuations in the energy analyzer measurements, we use special a compensative circuit loop.
