A high-temperature X-ray Lang camera has been designed to examine metal single crystals with a low dislocation density during the heating or cooling processes. The furnace for the camera was set on a goniometer-hand, therefore the setting of specimen is only slightly restricted. The camera can be used to take a topograph at any temperature up to 500℃with desired heating or cooling run. The spatial gradient of temperature in the exposing area of the specimen is less than1℃/mm, and tfie fluctuation of temperature during an exposure of about 30hours is less than ±0.5℃. Using this camera, several topographs were taken during a heating process of high purity aluminum single crystal. As the result it was ascertained that a screw dislocation converts to a helical dislocation by the generation of vacancies during the heating process.
