摘要：
A vacuum vessel is provided in which the main portion of a wall including an annular wall portion (1) and a plate-wall portion (2) is formed of ceramics such as silicon nitride. Because the generation of gas such as hydrogen is reduced from the wall of the ceramics vessel, extremely high vacuum can be generated in the interior of the vacuum vessel. Also, because the wall of the vacuum vessel has a high permeability with respect to a magnetic field and an electric field, the vacuum vessel can he applied to a particle accelerator as a vessel that can control in high precision charged particles therein with an electromagnetic field.
