Abstract

The advanced neutron facilities at low temperature below 1k are mainly based on helium refrigerator inserts and dilution that are used with orange cryostat (OC) or similar type of system. Recently global helium supplied problem causes the increased cost of liquid helium that has been raised the concerns about the affordability of cryostat. In this model the design and results are mainly based on the top loading cryostat which are cryogen free. The dilution refrigerator insert which are used in this model will provide sample environment for neutron scattering experiment that is seen between the temperature ranges from (36 mK to 293 mK). The refrigerator insert are operated in the continuous regimen. The cooling time and orange cryostat which are insert are always similar to each other. The performance criteria thar are created are based on the base temperature, rate of compatible and the cooling power which are present in the specification of the standard dilution refrigerator. This system will offers many types of operating parameters that are similar to orange cryostat but does not cause any complications of cryogens. In this model the first scientific result are obtained which are in the low temperature based neuron scattering experiment with the system are also discussed.
