Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific implementations described here are only used to explain the present invention, not to limit the present invention.

[0043] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. In contrast, when an element is referred to as being "directly" connected to another element, there are no intervening ele...

Abstract

The invention relates to a flat plate sample frame expansion structure used in vacuum. The structure is used to transfer a flat plate sample frame in a vacuum environment. The above-mentioned flat plate sample frame expansion structure used in the vacuum is fixedly connected with a flat plate sample frame tray in a detachable manner through a conversion adapter. An accommodation space accommodating the flat plate sample frame exists between the conversion adapter and the flat plate sample frame tray. The flat plate sample frame is fixed in the accommodation space in a detachable manner. A cylindrical sample frame gripper can be connected with the conversion adapter in a detachable manner. The purpose of transferring the flat plate sample frame and a sample thereof into low-temperature strong-magnetic-field equipment by the cylindrical sample frame gripper for sample replacement in the vacuum environment is achieved. Equipment using two types of sample frames is unified, and a vacuum measurement platform is built.

Description

technical field [0001] The invention relates to the field of vacuum instruments and equipment, in particular to an expansion structure of a flat sample holder for vacuum. Background technique [0002] In commonly used ultra-high vacuum measurement equipment, flat sample holders (supports) are often used to fix samples, and they are introduced into the equipment for measurement. The sample heating tables and rotating tables of many measurement equipment are also designed and manufactured based on flat sample holders. Moreover, the flat sample holder takes up little space and has a small heat capacity, which is very beneficial for use in low-temperature equipment, such as ARPES, MBE, etc. However, there is a type of vacuum low-temperature strong magnetic field equipment where the measurement device is located in the low-temperature Dewar, and the flat sample holder cannot be smoothly transferred to the measurement position. Therefore, the cylindrical sample holder is often use...
