Abstract
A cryostat configuration comprising an outer shell and a cryocontainer () for cryogenic fluid installed therein, wherein the cryocontainer () is connected to the outer shell via at least two suspension tubes (), and with a neck tube () whose upper warm end is connected to the outer shell and whose lower cold end is connected to the cryocontainer () and into which a cold head () of a multi-stage cryocooler is installed, wherein the outer shell, the cryocontainer (), the suspension tubes () and the neck tube () delimit an evacuated space, and wherein the cryocontainer () is moreover surrounded by at least one radiation shield which is connected to the suspension tubes () and optionally to the neck tube () of the cryocontainer () in a thermally conducting fashion, is characterized by a seal which can be manually and/or automatically actuated to separate the cold end of the neck tube () from the cryocontainer () in such a manner that fluid flow between the cryocontainer () and the neck tube () is minimized or completely interrupted. A cryostat configuration of this type ensures safe installation and removal of a cold head () into and from a neck tube () of a helium container ().
