Abstract: An apparatus may include a drift tube assembly having a plurality of drift tubes to conduct an ion beam along a beam propagation direction. The plurality of drift tubes may define a multi-gap configuration corresponding to a plurality of acceleration gaps, wherein at least one powered drift tube of the drift tube assembly is coupled to receive an RF voltage signal. The apparatus may also include a DC electrode assembly that includes a conductor line, arranged within a resonator coil that is coupled to receive a DC voltage signal into the at least one powered drift tube. The DC electrode assembly may also include a DC electrode arrangement, connected to the conductor line and disposed within the at least one powered drift tube.

Abstract: The air dome includes of one or several membrane shells made from textile-reinforced plastic film. These membrane shells are equipped on the entire surface of its underside with juxtaposed flat pockets which are heat-sealed on, bonded to, sewn on, or riveted on, each of which is designed to be open on one side, for inserting a multi-ply heat-reflective mat. Such mats are hybrid insulating mats having infrared-reflective metallized film or aluminum foils. Said mats can have multiple layers of absorption-reducing air bubble film to reduce the transmission heat losses. The openings of the pockets can be closed by means of a Velcro closure or zip fastener. A membrane is assembled from strip-shaped film webs, which are equipped along their longitudinal sides with a keder, and are connected with each other by connecting profiles in a force-locked manner.

Abstract: The air dome includes one or several membrane shells made from plastic film material. It has on at least one longitudinal or transverse side a frame construction which is connected to the bordering membrane material, and in the frame profile at least one transparent film is incorporated, for forming a window front. The air dome includes one or several membrane shells made of plastic film. The membranes are formed as double-ply membranes with an outer and inner membrane and divided into strips. The strips can be connected along their longitudinal edges by means of a keder having a keder connection profile in a force-locked manner. Surface heat-reflective mats can have multiple layers of absorption-reducing air bubble film to reduce the transmission heat losses. The construction of such a constructed air dome can be handled by two people as well as the dismantling and the transporting and interim storage.
