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 8):
The ion milling system according to  claim 1 , wherein\n the magnetic shield is configured with a ferromagnetic material that surrounds an outer periphery of the permanent magnet and that is disposed apart from the permanent magnet.
