Problems solved by technology

[0003] There are a large number of devices in the accelerator, the structure is complex, and the space is limited. The vacuum of the accelerator is ultra-high vacuum. Every time the carbon film is replaced, it will cause damage to the vacuum environment, and it needs to be re-evacuated, which greatly increases the installation time and reduces work efficiency. The operating cost of the accelerator

Abstract

The invention discloses a device for improving an ion charge state. The device comprises a membrane frame, a membrane frame mounting frame, a vacuum cavity, a vacuum corrugated pipe sealing mechanism, a driving mechanism, a base and a transmission rod, the membrane frame is used for mounting a carbon membrane; the membrane frame mounting frame extends into the vacuum cavity, and a plurality of membrane frames are arranged on the membrane frame mounting frame in the depth direction of the vacuum cavity at intervals; the vacuum cavity is connected to the front end of the vacuum corrugated pipe sealing mechanism in a sealed mode. The front end of the transmission rod penetrates through the vacuum corrugated pipe sealing mechanism, extends into the vacuum cavity and is connected with the membrane frame mounting frame; the rear ends of the vacuum corrugated pipe sealing mechanism and the transmission rod are connected with the driving mechanism; the vacuum corrugated pipe sealing mechanism and the driving mechanism are both arranged on the base. The carbon membrane can be replaced under the condition that the vacuum environment is not damaged, the working efficiency is greatly improved, the operation cost of an accelerator is reduced, and the operation efficiency of the accelerator is greatly improved.

Description

technical field [0001] The invention relates to a device for increasing ion charge state in an accelerator, which belongs to the technical field of accelerators. Background technique [0002] In the accelerator, after the ions generated by the ion source are initially accelerated to the high-voltage electrode, the charge state of the ions needs to be improved through the electron stripping device, so that the ions can obtain higher energy under the same electric field, especially in the storage ring of the accelerator. Ion implantation usually adopts the method of lift-off implantation. Therefore, the device for increasing the charge state of ions is an important device for heavy ion accelerators. Due to the high melting point of carbon, good chemical stability, and high mechanical strength of the carbon film, the accelerator generally uses the carbon film as the stripping body of the heavy ion external charge to obtain a higher charge state. For example, the Lanzhou heavy...
