Rutherford scattering diagnostic for the Madison symmetric torus reversed-field pinch

The technique of Rutherford scattering (RS) has been used (for the first ti me on a reversed-field pinch) to measure the bulk majority ion temperature on the Madison symmetric torus (MST). RS has been in routine operation on M ST since December 1999. The neutral beam source and electrostatic energy an alyzers which comprise the RS diagnostic were built by the Budker Institute of Nuclear Physics (Novosibrsk, Russia). The source is described in anothe r paper (Abdrashitov , these proceedings) and the analyzers are described. A data analysis routine has been developed which yields accurate fits to th e data, and estimates of errors in the fit parameters. Typical results are shown. (C) 2001 American Institute of Physics.
