A number of circular grooves are provided on the inner surface of the conductive insulator accelerating tube and a metal is metallized along the inside of the grooves.
In accelerating tubes that use conductive insulators, the dopant density on the surface becomes non-uniform, which may make the surface resistance of the conductive insulator non-uniform.
The structure of an acceleration tube is simplified and voltage distribution of the acceleration tube is smoothed.
bellows that link the vacum chambers
The acceleration tube of a device, such as an electron source device and an ion device, is composed of a semiconductive material, and voltages are applied to the both ends of the acceleration tube.
This device includes an acceleration tube with a mouth end and a detonation chamber arranged at a distance from the mouth end, and a supply device for supplying the material to the acceleration tube and/or the detonation chamber.
The acceleration tube having the simple structure and smooth voltage distribution is obtained.
One end of each hose pump within a pair is attached to the operating piston (17) on opposite sides thereof, and the other end is anchored to the unit which consists of the buoyant body (11) and the acceration tube (14).
