Abstract

In this study, a goniometer-type specimen stage for transmission electron microscopy is proposed. The specimen stage is mounted on the side of the vacuum chamber of a transmission electron microscope. A specimen is transported from the environment to the vacuum chamber via a holder, where positioning of the specimen is then conducted. The specimen stage comprises three translations and one rotational motion. As two translations are approximated linear motions, which are a part of the tilt motions, the term ‘goniometer’ is used. The actuation systems have been designed with consideration for the workspace and resolution. An air-locking device was also designed to separate the vacuum chamber from the atmosphere. Finally, the specimen stage was manufactured using aluminum and stainless steel to avoid the effect of a magnetic field. Experiments were then conducted to evaluate the performance of the proposed solution.
