Notes:
The set of diagnostics that are being installed in TJ–II are meant to cover the full photon energy range expected in TJ–II during the electron cyclotron resonance heating phase. The obtained information will be used to evaluate the energy contained in the superthermal electron populations and its possible relevance in the global power balance as well as for standard electron temperature estimations. Two NaI(Tl) detectors located at the equatorial plane of the machine will be used to analyze the highest energy photons (over 50 keV). One Si(Li) and a planar Ge detector will be used to obtain the emission spectra between 1 and 100 keV. Tomographic reconstruction of plasma emissivity (up to 10 keV) will be carried out using four p-n silicon photodiodes arrays of 16 detectors, located at the same poloidal section. An additional camera will be used to detect toroidal asymmetries. © 1999 American Institute of Physics.
