Abstract
Abstract : This manual was written to provide future users of Guinier-Lenne cameras in the Air Force Materials Laboratory with a clearly written set of instructions for set-up and operation of these cameras. This manual is intended to supplant the current manual, which is in poor condition and difficult to read. Borrowing information from the current manual, the Guinier-de Wolff operating instructions, and another manual, this author has attempted to gather as much relevant information as possible to instruct the reader in the operation of a Guinier-Lenne high temperature X-ray diffraction camera. This camera is designed to photographically record wide angle x-ray diffraction (WAXD) patterns as a function of temperature. Structural changes can be followed in this way and temperatures of those changes determined. The types of processes typically examined are: thermal expansion; phase changes; chemical transformations; and recrystallization of amorphous materials but any change in a specimen which is temperature dependent and results in a change in its WAXD pattern can also be examined with this camera. Keywords: Alignment; Focusing.
