6MeV Heavy Ion Beam Probe for the Large Helical Device

摘要

A 6 MeV heavy ion beam probe (HIBP) is designed for potential measurements on theLarge Helical Device (LHD). The article describes a method to control the 3-D probing beam trajectories in the helical magnetic field, an estimate of beam attenuation and energy reduction arising from the long paths in the plasma, and a cylindrical analyzer as a candidate of the energy analyzer.
