Abstract
Cooling the pyrolytic graphite analyser crystals of the IRIS spectrome ter to 25 K has proved to be very effective in suppressing the backgro und from thermal diffuse scattering and in improving the contrast of t he analysers. In this paper we show that a 12 times drop in background has been realised and that it would fall by an additional factor of 3 -4 by further reducing the analyser temperature to 5 K.
