    A new method is described for the measurement of soft x-ray (SXR) and ultrasoft x-ray (USXR) radiation of fusion plasmas. The system applies the microchannel plate (MCP) detector and can be used to measure the emitted radiation along 12 chords in different energy ranges. The operation of the MCP...

    In this paper we describe the bent crystal spectrometer of the Johann type built for the JET tokamak. This high resolution (λ/Δλ∼20 000) instrument is characterized by a very long focal length (25 m) allowing the crystal and the position sensitive detector to be placed outside the...

    A Bragg rotor spectrometer uses diffractors ranging from LiF (420) (2d=0.18 nm) to a multilayer mirror (Ni-C 2d=11.7 nm). The extension to longer wavelengths is particularly useful at JET, where radiated power and Z[sub eff] are usually dominated by light impurities such as Be and C, whose H-...

    Radiated power measurements taken during the thermal quench of a density limit disruption in the DIII-D tokamak [J. L. Luxon, Nucl. Fusion 42, 614 (2002)] demonstrate that ten times more power is radiated from the main chamber than is deposited into the divertor floor. This contrasts with the...

    One of the neutral-particle spectrometers used on the Doublet III tokamak has been improved and modified for use as an active charge exchange diagnostic on the DIII-D tokamak. The spectrometer employs a He stripping cell, parallel E and B analyzer fields, and a microchannelplate detector with 60...
