Suprathermal X-Ray Emissivity with 2nd and 3rd Harmonic Electron Cyclotron Heating in the TCV Tokamak
A multichordal, multichannel hard X-ray (HXR) pinhole camera, on loan from Tore Supra, is used on the TCV tokamak to study the spatial and spectral distribution of bremsstrahlung emission in the 10-200 ke V range. Photon detection is effected by a linear array of CdTe detectors  with an intrinsic energy resolution of ~7 keV. Eight energy channels, with adjustable thresholds, are available for each of 14 vertical viewing chords, which span the outboard half of the plasma cross section with partially overlapping Útendues and a radial resolution of approximately 2 cm on the midplane.
