  1. HT-7 diagnostics Autumn of year 2001

  2. Electro-magnetic • Standard measurements: Ip, Vp, position etc. • MHD: Mirnov coils • Diamagnetic: W, E • Internal inductance. Magnetic probe array • HT-7U R&D

  3. Electron density/temperature • 5 channel HCN laser interferometer • Langmuir probes (edge) • FSECE • ECE(FRC) • Soft-X ray PHA (3 channels) • TS • NPA (Ti)

  4. Fluctuation • Langmuir probes • Fast Ha array • CO2 laser scattering • Omegatron • Fast magnetic probes • Soft-X array • FRC-ECE

  5. Impurity • 10 channel visible monochromator • 7 channels vis-bremsstrahlung • 2 rotating mirror (UV) monochromators • 2 monochromators (OII, OV) • Two UV-VIS OSMA • IF periscope (LiI) • Omegatron

  6. Edge • Spectroscopy • Langmuir probes • Omegatron • Ha array

  7. Emission • 16 channels AXUV (bolometer-like) • 2 channels AXUV (total radiative power) • 2*43 XUV arrays • 2*37 SX arrays • 7 chs (H), 11chs (V), 4chs (T) HX monitor and PHA • 2 chs neutron monitor

  8. Which one can provide profiles • Electron density (HCN, LP) • Electron temperature (FSECE, FRC-ECE, TS, SXS) • Ion temperature (shot by shot up to 2 2? cm) • Radiative power (AXUV array) • Zeff and impurity, and Ha emission • fe(Ve) by HX (V) array • SX emission
