Observation unit, traveling wave tube unit, microwave tube unit, and observation method

Abstract

This makes it possible to suppress the transfer of external heat from the support points of the observation device to the observation device itself. [Solution] The observation unit comprises a housing in which the interior is a vacuum, a base housed in and fixed to the housing, and an observation device housed in the housing and supported by the base, wherein the base has a first magnet, and the observation device has a second magnet positioned to repel the first magnet and is supported away from the base.
