Abstract: A flat plate sample holder expansion structure used in a vacuum is configured to convey a flat plate sample holder in a vacuum environment, and detachably attached to a flat plate sample holder tray through an adapter. A receiving space for receiving the flat plate sample holder is provided between the adapter and the flat plate sample holder tray. The flat plate sample holder is detachably arranged in the receiving space. A cylindrical sample holder gripper is detachably connected to the adapter. The cylindrical sample holder gripper conveys the flat plate sample holder and samples thereon into a low-temperature, high-intensity magnetic field apparatus, thereby realizing an objective of replacing samples in the vacuum environment. A vacuum test platform is built by combining the apparatuses using the two types of sample holders.

Abstract: The present disclosure relates to an in-situ testing device including a measuring head, a drive mechanism, and a testing chamber. The testing chamber is provided with a first optical observation hole. The measuring head is provided with a second optical observation hole. The testing chamber is provided with an opening allowing the measuring head to pass. The testing chamber is further provided with a shielding door, and the drive mechanism is connected to the shielding door to drive the shielding door to move relative to the testing chamber, to open or cover the opening, thereby opening or closing the testing chamber.
