A Strip Type Transverse Quadrupole Component Driver

Abstract

The invention provides a strip type transverse quadrupole component exciter which can excite transverse quadrupole oscillation of an electron beam group in an electron accelerator storage ring, and study effects of the beam group transverse quadrupole oscillation on a beam performance, such as a beam current intensity and an operating point. The exciter consists of the following parts: four electrodes, eight HN electrode probe assemblies, a pipe, a left transition block, a right transition block, a shoulder ring, a flange welded inside the exciter, a loose sleeve, and the like. All the parts are welded. Two horizontal electrodes of the four electrodes are shaped like a letter "C", and two vertical electrodes are the plate electrodes. In the invention, a high frequency voltage is directly used to excite the beam group transverse quadrupole oscillation; compared with a method of adding an alternating current of a high frequency variation in a high frequency quadrupole magnet HFQM coil, the use method of the invention is simple and optimizing a design procedure is simple; a characteristic impedance matching is achieved simply through the use of Possion software and a least square method which are used for the optimization; and the strip type transverse quadrupole component exciter is simple in production, while the high frequency quadrupole magnet HFQM needs processing coils.

Description

technical field

[0001] The invention belongs to the field of charged particle accelerators, in particular to a strip-type transverse quadrupole component exciter, which is a device for stimulating transverse quadrupole oscillation of bundles in an electron storage ring. Background technique

[0002] Synchrotron radiation is electromagnetic radiation emitted by charged particles with a speed close to the speed of light along the tangential direction of the orbit when they move in a curved line, also known as synchrotron light. It was first observed in an electron synchrotron in 1947, hence the name synchrotron radiation, or synchrotron radiation for short.

[0003] The application research of synchrotron radiation began in the 1960s, and has experienced three development stages since then. Therefore, the existing synchrotron radiation devices are traditionally divided into three categories according to their main characteristics: the dual-purpose light source mainly for high-...
