Problems solved by technology

The device needs to open the accelerator shell frequently to replace the stripping tank and the type of stripping gas, which is inconvenient to operate; at the same time, because the stripping tank is placed on the high-voltage bench in the high-pressure area of ​​the accelerator head, the high-voltage bench is large in volume, which is not conducive to miniaturization

Abstract

The invention relates to a small serial accelerator stripping gas input device, and belongs to the technical field of accelerators. The device comprises an accelerator cavity, and a front accelerating tube, a gas stripping tube and a rear accelerating tube are sequentially arranged in the accelerator cavity in the length direction of the accelerator cavity. A stripping gas tank and an air pressure modulator used for adjusting stripping gas pressure are arranged outside the accelerator cavity, one end of the air pressure modulator is communicated with the stripping gas tank, the other end of the air pressure modulator is communicated with a quartz micropore pipe located in the accelerator cavity, and the other end of the quartz micropore pipe is communicated with the gas stripping pipe. The device is simple in structure and convenient to operate, and the stripping gas tank is placed outside the accelerator, so that frequent opening of the accelerator for replacement of the stripping tank and stripping gas types is avoided; the stripping gas with the required pressure is input from the ground potential to the high potential through the gas pressure modulator, and accurate control over the flow of the stripping gas is achieved.

Description

technical field [0001] The invention belongs to the technical field of accelerators, in particular to a stripping gas input device for a small tandem accelerator. Background technique [0002] The tandem accelerator accelerates negative ions in the first half of the accelerator and then enters the gas stripping system located in the middle of the accelerator to strip the negative ions into positive ions, and then uses the second half of the accelerator to re-accelerate the positive ions. Therefore, in order to realize gas stripping of ions, it is necessary to use a stripping gas. The conventional stripping gas input method is to place the tank containing the stripping gas in the high-pressure area of ​​the head of the accelerator. At the same time, in order to realize the flow control of the stripping gas, it is necessary to use an insulating rod extending from the ground potential to the gas flow control at the high potential. Valve to control the gas flow, such as figure...
