A HOLOGRAPHIC GRATING POLYCHROMATOR WITH OPTICAL FIBRE ENTRANCE AND EXITS FOR LASER SCATTERING EXPERIMENTS
A polychromator has been designed and constructed for the measurement of the electron temperature with high spatial resolution by Thomson scattering in the stabilized z-pinch EXTRAP. The design is centered on the use of low loss silica single fibres of 0.4 mm core diameter. The dispersive element is an aberration corrected concave holographic grating, specially designed to image the input fibre face onto the output fibre array with high efficiency. Very good stray light rejection is achieved due to the grating being the single optical element in the polychromator.
