SPATIAL SCAN DOUBLE CRYSTAL MONOCHROMATOR FOR JET
The spatial dependence of the main impurity concentrations of the JET plasma can be determined by absolute radiation measurements in a wide spectral range using a double crystal monochromator device, which enables spatial scan over the minor plasma radius during a time interval short compared to the plasma energy confinement time. The report describes the engineering design and tests for a spatial scan double crystal spectrometer that fulfills the conditions of crystal orientation according to the Bragg condition, of continuous spatial scanning using a swivel motion around the axis defined by the two crystal centres and of operating during the hydrogen and the deuterium experimental phases of JET.
