A 6 MeV heavy ion beam probe for the Large Helical Device

Abstract

A 6 MeV heavy ion beam probe (HIBP) is being designed for potential measurements on the Large Helical Device (LHD). This 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 for the energy analyzer.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
