Abstract

The invention relates to a Faraday cup and an ion beam measurement system. The Faraday cup comprises a front end part, a suppression assembly, an isolation assembly and a collector assembly which are stacked in sequence. An ion beam collecting opening is formed in the front end part; wherein the front end part is provided with a measuring port; the collector assembly comprises a first PCB substrate, the middle part of the first PCB substrate is provided with a first metal layer, and the edge of the first metal layer is provided with a first PCB insulating layer; a measured ion beam enters from an ion beam collection port of the front end part, is collected by the first metal layer after electrons are shielded by the suppression assembly, and is used for detecting beam data of the ion beam; according to the technical scheme, the collector assembly is made of the PCB, the PCB insulating layer on the PCB substrate and the metal layer in the middle of the PCB insulating layer are used for collecting ion beams, the Faraday cup structure is simplified by adopting the PCB technology, equipment installation is facilitated, the structural consistency is good, the production and manufacturing cost is low, and later maintenance is simple.

Description

technical field [0001] The present application relates to the field of ion beam technology, in particular to a Faraday cage and an ion beam measurement system. Background technique [0002] In the ion beam measurement technology, it is common to use a Faraday cage. The Faraday cage is an open copper barrel, which is used in the Faraday cage experiment to measure the charge of the bunch and suppress the secondary electrons in the neutron generator. When measuring the ion beam, the principle is to let all the charges of the beam be deposited on the Faraday cup, and the Faraday cup can measure the charge of the beam more accurately. [0003] Due to the simple principle and easy operation of the Faraday cup, it is one of the most widely used methods to measure the charge of the cluster at present, but the disadvantage of the Faraday cup method is that the beam is completely deposited on the Faraday cup, and the beam is completely destroyed, which is difficult to achieve.
