AI Technical Summary

Technical Problem

In existing isotope electromagnetic separators, there is high-intensity isotope sputtering contamination between adjacent beam receiving pockets, which affects the purity and abundance of the separated products. At the same time, the integrated conductive panel cannot monitor beam position shift, making dynamic correction difficult.

Method used

Multiple tungsten rods and baffles are set on the receiver panel. The tungsten rods are used to measure the beam intensity and width, and the baffles are used to block sputtered particles from adjacent beams. The positions of the tungsten rods and baffles are determined by calculating the separation radius, valley width, and beam spot width.

Benefits of technology

It improves the purity and abundance of isotope separation, reduces adjustment time, enhances beam alignment performance, and increases equipment operating efficiency and capacity.

Abstract

The invention discloses a beam separation device and method based on an isotope electromagnetic separator. The device comprises a receiver panel arranged on a receiver of the isotope electromagnetic separator, a beam receiving pocket, an insulating block and a plurality of tungsten rods used for measuring beam intensity and width. And the baffle blocks are used for blocking particles sputtered in the adjacent beam receiving pockets. The method comprises the following steps: calculating a separation radius R, a valley region width delta R and a beam spot width W of the electromagnetic separator; according to the separation radius R, the valley region width delta R and the beam spot width W, the fixed position of the tungsten rod is obtained; a beam trajectory diagram is obtained according to the separation radius R, the valley region width delta R and the beam spot width W; and the fixed position of the stop block is calculated according to the beam trajectory diagram. According to the method, the target isotope abundance is improved from 98% to 99.5%. The time for adjusting the beam is reduced, the loss caused by the fact that the ion beam is not aligned with the receiving seam is reduced, and the isotope productivity is improved: the productivity of 176Yb is improved from 18g / year to 22g / year.
