。 Vacuum ducts for charged particle beams used in particle acceleration or accumulation systems that use superconducting saddle-type dipole coils as deflection magnets have slits that allow the emitted light from the charged particle beam to pass through, and prevent gases emitted from the duct surface. A non-magnetic barrier is provided to suppress diffusion into the charged particle beam passage area, or the barrier and the side wall of the duct are provided to surround the charged particle beam passage area. A vacuum duct for accelerating and accumulating charged particles, characterized in that an ion pump for absorbing degassing is provided in the space between the barrier and the vacuum duct.
