Abstract

The Helicity Injected Torus with Steady Inductive current drive (HIT-SI) device is a spheromak which uses two inductively driven helicity injectors to provide constant helicity injection. The HIT-SI diagnostic set includes 96 3-D magnetic surface probes, 20 toroidal flux loops, an internal array of three stems of 3-D magnetic probes, a far infrared interferometer, a SPRED diagnostic, two tangentially viewing vacuum ultraviolet (VUV) spectrometers, a bolometer, a Zeff diagnostic, H-alpha detectors, a time integrated CCD camera, and Ion Doppler Spectroscopy (IDS). In addition, a multi point Thomson Scattering system, a microwave interferometer/polarimeter, injector voltage probes, an edge Langmuir probe array, and soft X-ray camera are under development.
