Abstract: A holding apparatus for at least one storage medium has a housing in which a supporting structure is arranged. The supporting structure is in this case connected to the housing with vibration damping via a damping device. A storage medium is arranged in the supporting structure. The storage medium is bounded in a pressuretight manner from an external atmosphere. A cooling element is provided for cooling the storage medium.

Abstract: A holding device for an optical element, is formed at least in part, of a silicon-containing aluminum material.

Abstract: The invention relates to an apparatus for production of an electromagnetically shielded connection between a plug arrangement (which has at least one plug) of a first unit and a socket arrangement, which has at least one corresponding socket, of a second unit. The at least one plug and the at least one socket form a plug connection when connected to one another. The plug connection is surrounded by a shielding device which provides good electromagnetic shielding for it and is formed by the at least one plug and the at least one socket independently.
