Abstract

The invention discloses a micron dimension conversion target device for electron beam emittance measurement. The micron dimension conversion target device includes a lower circular seat, the upper end face of the lower circular seat forms a circular groove by recessing inward along the axis and further includes an upper circular seat matched with the lower circular seat, the lower surface of the upper circular seat is provided with a protruding ring protruding downwards and matched with the circular groove of the lower circular seat, and after the protruding ring of the upper circular seat is inserted into the circular groove of the lower circular seat, the film paved on the lower circular seat is expanded to form a minute surface. The micron dimension conversion target device overcomes the defects that a quartz slice is small in size, inconvenient to clean, easy to damage, and inconvenient to install, achieves the aims of simple use, convenient maintaining, and low cost, has the same measurement precision in the various calibers having the diameter ranging from 30-200mm, and greatly improves the adaptive caliber relative to the quartz slice only allowing the diameter of 50-60mm.

Description

technical field [0001] The invention relates to the technical field of electron beam emittance measurement, in particular to a micron-scale conversion target device used for electron beam emittance measurement. Background technique [0002] Electron beam emittance measurement technology in the accelerator field is an important test technology in the accelerator development process. The performance status of the electron beam can be obtained through the measurement of the electron beam emittance, which is of great significance for the debugging of the accelerator. . In the emissivity measurement technology, there is a measurement technology based on the Cerenkov radiation principle, but this measurement technology requires the conversion target thickness to be extremely thin, preferably on the order of microns, and requires the conversion target plane to achieve a mirror effect. Otherwise, it will bring great errors to the measurement and even untrue measurement results. ...
