Problems solved by technology

[0005] 1) The internal parameters of the target capsule cannot be measured non-destructively. The existing method requires destructive cutting of the target capsule. After the measurement, the target capsule is destroyed and cannot be applied to the next step of process processing or target shooting experiment;

[0006] 2) Insufficient comprehensive measurement capability, each instrument can only measure one or two parameters, and the comprehensive parameter measurement of the target pellet needs to be repeatedly installed and adjusted on different instruments, which is inefficient and the value reference is not uniform;

[0007] 3) The measurement process of geometric shape and physical property parameters is separated, which cannot fully reveal the phenomenon and law of structural changes occurring in the process of pellet preparation and nuclear fusion reaction;
