Abstract: A coupling device that couples with a cart includes a coupling portion that couples with the cart, a base portion that guides the coupling portion, and a driving motor that drives the coupling portion. The driving motor drives and controls the coupling portion so as to be changeable among a first state in which the coupling portion is housed, a second state in which the coupling portion is capable of coupling with the cart, and a third state in which the coupling portion couples with the cart. With the coupling portion and a side frame of the cart facing each other, the coupling portion changes from the second state to the third state, thereby causing the coupling portion and the side frame to be coupled to each other.

Abstract: A primary electron beam applied to a thinned sample excites Auger electrons on a surface of the thinned sample, and most of the primary electron beam is transmitted by the thinned sample, scattering and reflection are restrained and an Auger electron generation area is micrified. A primary electron beam transmitted by the thinned sample passes through a hole and is directed to a Faraday cup disposed immediately below the sample. The primary electron beam entering the Faraday cup is scattered and reflected within the Faraday cup and effectively absorbed and captured by the Faraday cup. By maintaining the potential of the Faraday cup at a ground potential during the analysis, stable data are obtained.
