摘要: A simulation device calculates a detection number of electrons generated by charged particles radiated to a sample by a simulation and generates a simulation image of the sample. The simulation device holds penetration length information (272) in which incidence conditions of the charged particles and a penetration length are associated with each other, sample configuration information (271) which shows a configuration of a sample, and emission electron number information in which the incidence conditions of the charged particles and an emission electron number are associated with each other. The simulation device calculates the number of electrons emitted from a predetermined incidence point, on the basis of incidence conditions at the predetermined incidence point, the penetration length information (272), the sample configuration information (271), and the emission electron number information.

摘要: The system described herein relates to a particle beam apparatus for analyzing and/or for processing an object and to a method for operating a particle beam apparatus. The particle beam apparatus is designed for example as an electron beam apparatus and/or an ion beam apparatus. The particle beam apparatus comprises a beam deflection device, for example an objective lens, which is provided with a first coil and a second coil. The first coil is operated with a first coil current. The second coil is operated with a second coil current. The first coil current and/or the second coil current may always be controlled in such a way that the sum of the first coil current and the second coil current (the summation current) or the difference between the first coil current and the second coil current (the difference current) is controlled to a setpoint value.
