Abstract: A method of opening a vacuum vessel in a vacuum space where the vessel is to be opened without producing undesired elements into the vacuum space. The walls of the vessel must comprise two parts that are connected together by means of a closure member having a U-shaped cross-section. The closure member is constructed of two flat rings that are connected at their inner edge. The method step comprises rotating the parts of the wall in opposite directions until the joining of the edges fractures.
