Abstract
A spin polarimeter includes: a particle beam source or a photon beam source that is a probe for a sample; a sample chamber in which the sample is accommodated; a spin detector that includes a target to be irradiated with an electron generated from the sample by a particle beam or a photon beam from the probe, and a target chamber in which the target is accommodated, and is configured to detect a spin of the sample by detecting an electron scattered on the target; a first exhaust system that is configured to exhaust the sample chamber; a second exhaust system that is configured to exhaust the target chamber; and an orifice that is disposed between the target chamber and the sample chamber.
