The DIII-D E/parallel/B charge exchange diagnostic

Creators

Description

One of the neutral-particle spectrometers used on the Doublet III tokamak has been improved and modified for use as an active charge exchange diagnostic on the DIII-D tokamak. The spectrometer employs a He stripping cell, parallel /rvec E/ and /rvec B/ analyzer fields, and a microchannel plate detector sixty energy channels for each of two neutral particle masses. Improvements to the diagnostic include better radio frequency and gamma ray and complete instrumentation of all energy channels. Calibration results for H and D are similar to those reported previously. The instrument views across one of the DIII-D heating beams which can be modulated to provide local neutral doping. The analyzer is scanned shot-shot to measure neutrals with pitch angles between /approximately/5/degree/ and /approximately/110/degree/. 34 refs., 5 figs
