Abstract:
To provide an ion milling system that can suppress an orbital shift of an observation electron beam emitted from an electron microscope column, the ion milling system includes: a Penning discharge type ion gun  100  that includes a permanent magnet  114  and that generates ions for processing a sample; and a scanning electron microscope for observing the sample, in which a magnetic shield  172  for reducing a leakage magnetic field from the permanent magnet  114  to the electron microscope column is provided.

Claim (Index 10):
The ion milling system according to  claim 2 , wherein\n the ion gun includes an ion gun base that holds the permanent magnet and the accelerating electrode, the accelerating electrode is a structure split into three parts that are an accelerating electrode guide member, a first accelerating electrode member, and a second accelerating electrode member, the accelerating electrode guide member is formed from a material other than a ferromagnetic substance and secured to the ion gun base, the first accelerating electrode member is formed from the ferromagnetic substance and installed on an outer side of the accelerating electrode guide member, the second accelerating electrode member is formed from the ferromagnetic substance and installed by being positioned by the accelerating electrode guide member and the first accelerating electrode member, and the first and second accelerating electrode members are secured by a magnetic field of the permanent magnet.
