A reflective optical transport system for ultraviolet Thomson scattering from electron plasma waves on OMEGA

A reflective optical transport system has been designed for the OMEGA Thomson-scattering diagnostic. A Schwarzschild objective that uses two concentric spherical mirrors coupled to a Pfund objective provides diffraction-limited imaging across all reflected wavelengths. This enables the operator to perform Thomson-scattering measurements of ultraviolet (0.263 mu m) light scattered from electron plasma waves. (C) 2012 American Institute of Physics.
