Abstract

SPIDER, a prototype negative ion source with low voltage extraction for the ITER neutral beam injector will be equipped with a set of diagnostics in order to qualify and optimize the neutral beam for ITER. In particular, the Visible Tomography diagnostic will estimate the uniformity of the beam using a set of linear CCD cameras, while Emission Spectroscopy will measure the spatial variation of plasma parameters in the RF plasma source and evaluate the divergence of the extracted beam, analyzing the spectrum collected over multiple lines of sight. This paper presents the optical layout of the lines of sight and detection heads of Tomography and Spectroscopy and the required accuracy in their alignment, proposing also alignment criteria. © 2013 IEEE.
