Description
Technical Field
The application relates to the technical field of high-energy light source vacuum pipelines, in particular to a flange assembly for a high-energy light source vacuum pipeline and a sealing gasket thereof.
Background
Modern particle accelerators and storage rings are constantly pursuing high flow and brightness. High energy, rigid beams, generally have two approximations. The rigid beam is approximate, namely the beam is rigid when passing through a vacuum pipeline with a discontinuous structure, the influence of a tail field on the beam is a perturbation quantity, the longitudinal and transverse movement of the beam cannot be influenced, and the longitudinal distance between the source beam and observed particles is unchanged in a period of action time; the second is pulse approximation, i.e. the integral of the tail field in a period of time is acted on the beam motion, and the tail field has no meaning on the instantaneous action of the beam. The tail field is the transient response of the beam current to the vacuum structure, and for the purpose of measuring the effect, the integral of the tail field along a ring or a plurality of vacuum pipelines is commonly used to describe the tail field, namely the tail field potential.
When the beam passes through the vacuum pipeline, a tail field generated by interaction with the surrounding environment reacts on the beam, disturbance is generated on the motion of the beam, energy loss and frequency shift of the beam are caused, and when the strength of the tail field is large enough, instability of the motion of the beam can be caused, and even beam loss is caused. Beam instability caused by the tail field or impedance is called beam collective instability (collecting instability). For relativistic beam current, the field generated by the beam current in free space or an ideal smooth conductor pipeline is vertical to the motion direction, and the beam current collective effect cannot be generated.
Therefore, the beam current collective effect is required to be generated by non-relativistic beam current or non-ideal conductor or discontinuous geometric structure of the vacuum pipeline. Ionization of residual gas in the pipeline by proton beams, impact of lost proton beams on the pipeline wall, stripping action of injected stripping films, secondary electron emission and the like can generate a large amount of electrons, and therefore electron cloud is formed in the vacuum pipeline. The electron cloud and the proton beam are bound to each other and oscillate, possibly causing instability, i.e., electron cloud instability. When the beam intensity in the storage ring is higher and higher, the effects can seriously affect the beam performance, and further affect the stability of the beam or the brightness of the collider.

Referring to fig. 1, the present embodiment provides a gasket for a flange assembly of a vacuum tube for a high-energy light source, the vacuum tube for a high-energy light source being made of an austenitic material (e.g., 304 or 316L stainless steel), and the gasket being made of an annealed copper material. The seal gasket specifically includes: the gasket comprises a ring-shaped gasket body 10 and elastic bulge groups respectively arranged on two side surfaces of the ring-shaped gasket body 10.

The elastic protrusions 20 on one side of the annular gasket body 10 are arranged around the inner ring of the annular gasket body 10 at equal intervals, and the elastic protrusions 20 on the other side of the annular gasket body 10 are arranged around the inner ring of the annular gasket body 10 at equal intervals.
As mentioned before, the high-energy light source vacuum pipeline flange component comprises two flange plates at the connecting ends of two adjacent vacuum pipelines, and the two flange plates are fixedly connected through the sealing gasket so as to seal the gap between the two flange plates. Referring to fig. 4 and 5, flanges 31 are provided at both ends of the vacuum pipes 30, and the gasket is clamped between the flanges 31 at the connecting ends of two adjacent vacuum pipes 30 to seal the gap between the two flanges 31. A circle of convex edges 311 is arranged on the end surface of the flange plate 31, the circumferential size of the circle of convex edges 311 is smaller than that of the sealing gasket (annular gasket body), and meanwhile, the distance from the top end of the circle of convex edges 311 to the end surface of the flange plate 31 is basically equal to the distance from the top end of each elastic bulge 20 to the side surface of the annular gasket body 10. The ring of convex edges 311 on the two flanges 31 are pressed against the two side surfaces of the annular gasket body 10, so that the gap between the two flanges 31 is sealed, and a sealed environment is provided for the high-energy light source vacuum pipeline. Meanwhile, the elastic bulge groups on the two side surfaces of the annular gasket body 10 generate certain elastic deformation under the extrusion effect and are communicated with a gap formed between the inner cavity of the vacuum pipeline 30 and the two flange plates 31, the elastic bulge groups are wrapped in the gap by a circle of convex edge 311, and the gap is sealed by a circle of convex edge 311, so that the impedance of the high-energy light source vacuum pipeline is reduced.

In one embodiment, one end of the first fin 21 is fixedly arranged at the edge of the inner ring of the annular gasket body 10 in the circumferential direction, and the surface of the first fin 21 facing the center line direction of the annular gasket body 10 and the circumferential surface of the inner ring of the annular gasket body 10 are in the same plane. It can be understood that the fins extend from the axial edge of the inner ring of the annular gasket body 10 along the central line direction of the annular gasket body 10 to the direction away from the annular gasket body 10, and then the L-shaped structure is formed by bending the fins.
