Field: Control (Instruments)
Classification: CPC G  H | IPC G

Claim 15:
16. The diagnosis system according to claim 13,
wherein the first tracking information describes a change over time in the movement locus of the first moving mechanism,
the second tracking information describes a change over time in the movement locus of the second moving mechanism,
the computer system estimates a change in the movement locus of the first moving mechanism based on the change over time in the movement locus of the first moving mechanism that describes the first tracking information,
the computer system estimates a change in the movement locus of the second moving mechanism based on the change over time in the movement locus of the second moving mechanism that describes the second tracking information, and
when the first charged particle beam device and the second charged particle beam device execute the same operation, the computer system determines whether or not the same position on the sample is irradiated with the charged particle beam repeatedly an allowable number of times based on whether or not the estimated change in the movement locus of the first moving mechanism and the estimated change in the movement locus of the second moving mechanism overlap each other on the sample.
