Abstract

The invention relates to an ion transportation device. The ion transportation device is characterized by comprising a connecting sleeve, a collection slit plate, a collection lens group, a correction magnet, a molecular pump and an auxiliary collection lens group, wherein collection slits are arranged on the collection slit plate, the collection lens group, the correction magnet, the molecular pump and the auxiliary collection lens group are sequentially arranged on the rear side of the collection slit plate according to the transmission direction of ion beams, and the connecting sleeve is nested on the collection slit plate and the collection lens group. The ion transportation device provided by the invention is used for collection and transportation of ions in an ion laser accelerator; one part of the ion transportation device can be inserted into the inside of a laser target chamber due to the arrangement of the connecting sleeve, so that the distance between the ion transportation device and a laser target can be further reduced, the control of ion beams by the ion transportation device is flexible and high-efficient, and therefore the ion transportation device can meet different application requirements.

Description

technical field [0001] The invention relates to an ion transport device, in particular to an ion transport device in a laser accelerator. Background technique [0002] Many research institutes in the world are conducting research on the application of laser accelerators, but the research is still in the exploratory stage. This is because the ion beam produced by the laser accelerator has the characteristics of short pulse, high current intensity, and large energy dissipation, which has caused great troubles to the application of the ion beam. The pulse width of the ion beam generated by the laser accelerator is only tens of picoseconds, and each pulse contains 10 8 -10 11 ions, so the pulse current intensity can reach the ampere level. Moreover, the size of the initial beam spot of the ion beam is equal to that of the laser focal spot, which is only a few microns, resulting in a very strong space charge effect, a large envelope of the ion beam during transmission, and low...
