Abstract

Innovative charge-exchange recombination spectroscopy (CHERS), motional Stark effect (MSE), and Rutherford scattering diagnostics are now in operation on the Madison Symmetric Torus (MST) reversed-field pinch (RFP). The CHERS diagnostic measures impurity ion flow and temperature, localized to 2 cm with high time resolution (similar to 100 kHz). A spectral MSE diagnostic has been in use for five years, measuring vertical bar B vertical bar down to 0.2 T with high precision (similar to 2 and good time resolution (similar to 100 kHz). The Rutherford scattering diagnostic has demonstrated the robustness of this technique for reliable measurement of majority (D) ion temperature, also with high time resolution. MST is a large RFP (R= 1.5 m, a= 0.52 m) operated at moderate current (I-p
