SANS Low Temperature Vessel for Powders
This vessel was manufactured using BeCu for the main vessel body and components. Sapphire windows allow for a neutron optical sight through the center of the sample position. The vessel is used in conjunction with a low temperature closed cycle refrigerator (CCR) equipped with a �tail set� with SiO2 windows. The total sample volume is 2.2 cm3; nevertheless, an effective neutron beam cross-section area of 0.3 cm2 and a neutron beam divergence of 15� must be taken into consideration when designing an experiment.
