A glass-plastic cryostat for SQUID-magnitometry includes two vessels, the outer and the inner ones, those have usually cylindrical form, in the gap between two vessels radiation screens and screen-vacuum insulation are placed, the inner vessel includes a helium tank, flange, mouth and tail element, the outer vessel is hermetically fixed to the flange and has larger dimensions compared to the inner one, in the bottom of the tail element of the outer vessel depressions are provided, the number of those is equal to the number of measuring channels, all the elements of the inner and outer vessels are made of composite materials, on the basis of binding agent and glass, carbon or mineral fiber. The inner vessel is made with separate tail elements, the number and dimensions of those correspond to the number and dimensions of the measuring channels, the outer vessel is made with ergonomic tail element with rounded form in such a way that it smoothly goes to cylindrical body of the outer vessel, the lower ends of the inner tail elements are placed to respective depressions in the bottom of the outer vessel. |
