Abstract
Method and system are offered which evacuate a sample holder such that a sample can be inserted into the electron optical column of a microscope while certainly preventing exposure to the atmosphere. The system has pumping control means for controlling a vacuum pumping sequence. The inside of a microscope goniometer is evacuated to a given low vacuum state while the pressure inside a hermetic sample chamber is kept constant by the pumping control means. Then, the partition valve of the sample chamber is opened by the pumping control means and the sample chamber is brought to the low vacuum state. Then, the goniometer and sample chamber are brought to a high vacuum state by the pumping control means. Then, the sample is brought into the front end of the goniometer, and the sample holder is inserted into the electron optical column.
