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 tandem accelerator stripping gas input device, belonging to the technical field of accelerators. A stripping gas tank and a gas pressure modulator for adjusting the pressure of the stripping gas are arranged outside the cavity. One end of the gas pressure modulator is communicated with the stripping gas tank, and the other end is communicated with a quartz microporous tube located inside the accelerator cavity. The quartz microporous The other end of the tube is communicated with the gas stripping tube. The invention has simple structure and convenient operation. By placing the stripping gas tank outside the accelerator, frequent opening of the accelerator is avoided to replace the stripping tank and the type of stripping gas; potential to achieve precise control of stripping gas flow.

Description

technical field [0001] The invention belongs to the technical field of accelerators, in particular to a small tandem accelerator stripping gas input device. Background technique [0002] In the tandem accelerator, the negative ions are accelerated in the first half of the accelerator and then enter the gas stripping system located in the middle of the accelerator to strip the negative ions into positive ions, and then use the second half of the accelerator to re-accelerate the positive ions. Therefore, it is necessary to use a stripping gas in order to achieve gas stripping of ions. The conventional stripping gas input method is to place the tank containing stripping gas in the high-pressure area of ​​the accelerator head. At the same time, in order to realize the flow control of stripping gas, it is necessary to use an insulating rod to extend from the ground potential to the gas flow control at the high potential. valve to control the gas flow, such as figure 1 shown. T...
