<p>The invention relates to a vacuum chamber (1) comprising at least one ceramic isolating cylinder (16) with two face ends, wherein at least one of the two face ends (2) of the ceramic isolating cylinder (16) is closed by a metallic cover (3) comprising an outer and an inner part (4, 5), wherein a distal end of the outer part (4) of the metallic cover (3) is thinner relative to the remainder of the outer part (4) of the metallic cover (3) and forms a metallic lid (6), wherein the metallic lid (6) is connected to at least one of the two face ends (2) of the ceramic isolating cylinder (16) in a vacuum tight manner. According to the invention the metallic cover (3) is formed in one piece and fits with the inner part (5) of the metallic cover (3) at an inner girthed area (7) of the ceramic isolating cylinder (16) to realize a self-centering of the metallic lid (6) to at least one of the two face ends (2) of the ceramic isolating cylinder (16).</p> |
