Abstract
A vacuum pipe for use in a synchrotron orbit radiation device includes a vacuum pipe body made of a thin non-magnetic material surrounding a charged particle beam propagating on an annular path, a port portion cell interposed in the vacuum pipe body surrounding part of the path, and a port mounted on the port wall tangential to the path for introducing radiation. The vacuum pipe body has a smooth inner wall surface and reinforcing ribs on an outer wall surface. A wall of the port portion cell located on an outer diameter side of the path is oblique to the wall of the port portion cell on the inner diameter side.
Claims7
A vacuum pipe for use in a synchrotron orbit radiation device comprising:
- a vacuum pipe body for surrounding part of an annular path traversed by a charged particle beam, said vacuum pipe body being formed of a thin tube made of a non-magnetic material and having a smooth inner wall surface and an outer wall surface with a plurality of reinforcing ribs disposed on the outer wall surface transverse to the path;
- and
- at least one port portion cell having opposed ends and interposed between parts of said vacuum pipe body surrounding part of said path, said port portion cell being formed of a thin tube made of a non-magnetic material and having a smooth inner wall surface and an outer wall surface with a plurality of reinforcing ribs disposed on the outer wall surface transverse to the path, said port portion cell including a port wall transverse to and extending from said vacuum pipe body at one end of said port portion cell, a tubular port mounted on and extending from said port wall tangential to the path for introducing radiation, wherein said port portion cell has an inner diameter wall located inside the path and an outer diameter wall located outside the path, deviating from said outer wall surface of said vacuum pipe body toward said tubular port, oblique to said inner diameter wall, and substantially tangent to the path.
