TY - JOUR AU - Thomas, D E AB - The paper describes a new form of Sauter's X-ray goniometer which secures the necessary synchronism between the rotations of the crystal and film by driving them with two small synchronous A.C. motors, instead of by using gearing. The film can be used normal to the incident X-rays or inclined at an angle (usually 45) so that the more deviated and weaker reflexions fall less obliquely on the film than when in the normal position. In both these film positions equatorial and layer line reflexions can be obtained. The theory of the apparatus is explained and it is shown how the reciprocal lattice can be obtained from the polar co-ordinates on the film.
