High energy strong current accelerator Faraday cup

Abstract

The invention provides a Faraday cylinder for a high-energy high-current accelerator. The Faraday cylinder is mainly characterized in that the head portion of the Faraday cylinder is connected with a driving device through an adapter flange and a loose flange, and the head portion of the Faraday cylinder and the driving device are mutually independent. According to the Faraday cylinder for the high-energy heavy-current accelerator, a water inlet pipe, a water outlet pipe, a high-voltage cable and a signal cable on the head portion of the Faraday cylinder pass through the adapter flange and the loose flange and pass through the support cylinder of the driving device to extend to an atmosphere end. The adapter flange and the loose flange are each provided with a cutting edge, a copper pad is additionally arranged between the two flanges, and the two flanges are connected and sealed through a bolt, such that an atmosphere is isolated from a vacuum. According to the invention, the direction of the head portion of the Faraday cylinder can be conveniently adjusted, the head portion of the Faraday cylinder can be conventionally replaced, and convenience is brought to installation and maintenance. The interception surface of the Faraday cylinder and a water cooling body are in surface contact with each other, such that the water cooling effect is effectively enhanced. The conic node of the interception surface is easy to process, and the processed conic node is a point; and the field angle at the bottom of a cone effectively reduces the axial length of the cone.

Description

technical field [0001] The invention relates to a beam current diagnostic equipment used in an accelerator device, in particular to a Faraday cage used in a high-energy intensive current accelerator device. Background technique [0002] The Faraday cup is an intercepting beam diagnostic device commonly used in accelerator devices. Its function is not only to block and intercept the beam, but also to measure the intensity of the beam. Because it was first designed and used by Faraday, it is often called a Faraday cage. Its structure is generally a cylindrical collecting electrode. When the beam (a collection of charged particles) bombards the electrode and is intercepted and collected by the electrode, the charge carried by the beam flows through the resistor to form a loop, thereby measuring the current intensity of the beam. . [0003] The Faraday cage is an intercepting beam diagnostic device. When the beam is intercepted, its energy will be deposited on the intercepting...

AI Technical Summary

Problems solved by technology

[0008] 1) Solve the problem that the traditional Faraday cage is easily damaged in the case of high energy and strong flow because of its structural shape and non-surface contact between the intercepting surface and the water cooling body;

[0009] 2) Solve the problem that the traditional Faraday cage cannot be replaced and repaired after the Faraday cage is damaged because the head of the Faraday cage and the driving device are designed as a whole;

[0010] 3) Solve the problem that the traditional Faraday cage is inconvenient to install because the head of the Faraday cage and the driving device are designed as a whole, and the angle of the head of the Faraday cage is fixed.
