Title Ultra-low temperature sample Environment for Neutron Scattering Experiments
Contributors
Abstract Today almost a quarter of all neutron scattering experiments performed at neutron scattering facilities require sample temperatures below 1K. A global shortage of helium gas can seriously jeopardize the low temperature experimental programs of neutron scattering laboratories. However the progress in cryo-cooler technology offers a new generation of cryogenic systems with significantly reduced consumption and in some cases a complete elimination of cryogens. Here we discuss new cryogen free dilution refrigerators developed by the ISIS facility in collaboration with Oxford Instruments. We also discuss a new approach which makes standard dilution refrigerator inserts cryogen-free if they are used with cryogen-free cryostats such as the 1.5K top-loader or re-condensing cryostat with a variable temperature insert. The first scientific results obtained from the neutron scattering experiments with these refrigerators are also going to be discussed.
