Abstract

Specimens are prepared for examination by transmission electron microscopy techniques by making them suitably thin by using an ion source which is cooled so that the specimen can be placed close to the cathode of the ion source and the concentration of the beam impinging on the specimen to thin it is increased whereby to improve the rate at which the specimen is thinned to a required thickness without deleteriously affecting its structure. The specimen may be held stationary or may be rotated and be so disposed that the ion beam impinges normally or at any convenient angle, e.g. 60 DEG , thereto. Initially, one side of the specimen may be irradiated by the ion beam for a short while, the specimen then being reversed and the other side irradiated to the required thickness, which may be determined by monitoring the ion current penetrating the specimen.
