Гелиевый криостат для исследования свойств массивных твердотельных резонаторов при глубоком охлаждении
Abstract
A new helium cryostat for studies of properties of massive (in order of dozens of kilogram) solid acoustical and optical resonators is modernized and tested. The full cycle of cooling from the room temperature to nitrogen and helium temperature has been held. The dynamics of the model acoustical characteristics of the model was studied at different stages of cooling. The operational parameters of new cryostat were measured, and the mounting of optical inputs was completed for the study of models with cryogenic mirrors.
