  • Sample exchange device and charged particle beam device
    Patent number: 11205558
    Abstract: A sample exchange device includes a first transport mechanism that includes a grip portion that grips a sample holding member and transports a sample holding member to a sample exchange chamber, a cooling unit that cools the sample exchange chamber, fiber sensors that detect whether or not the grip portion of the first transport mechanism grips the sample holding member in the sample exchange chamber, and a control unit. The control unit turns on the fiber sensors when the grip portion of the first transport mechanism enters the sample exchange chamber and turns off the fiber sensors after it is detected whether or not the grip portion of the first transport mechanism grips the sample holding member.
