摘要： A linear particle accelerator with high accelerating gradient, provided with a body comprising a compact primary vacuum chamber (3, 3') made of high-conductivity material, wherein said chamber (3, 3') comprises at least three adjacent, coaxial accelerator cells, having a cylindrical symmetry shape, configured to operate in the standing wave configuration in the π mode; wherein said accelerator cells are joined together and locked by tightening means and externally welded by means of TIG (Tungsten Inert Gas) welding to avoid high temperature treatments; wherein each cell has a ring beam forming an RF tooth with a contact angle between 10° and 30°, arranged on at least one contact surface between the assemblable parts to form said cells, which tooth is configured to provide, upon the actuation of said tightening means, the RF contact and the vacuum seal.
