Grazing incidence VUV duochromator with metallic multi-anode microchannel plate detectors for Tokamak plasma spectroscopy

Technical Report:

Abstract

The performance of a grazing incidence (85 deg) VUV duochromator using two proximity focused metallic multi-anode microchannel plate detectors is described. The system, using standard photon counting techniques directly on the array of 10 straight anodes, has a total coverage of 5-230 nm, with a 0.13 nm (one anode) spectral resolution; each detector (centered on the Rowland circle and mounted perpendicularly to the diffracted ray) covers a 1.33 nm region (the spectral range being independent of the central wavelength value). A maximum permissible counting rate of 2 x 10{sup 6} Hz has been obtained, thus allowing sub-ms time resolution. Examples of the operation of this system on the Tore Supra tokamak are described.
