Ong Sing PoenGO’s and at odds with financial practice and orthodoxy it grew into well formulated policy adopted by a wide range of investors. Academic literature on SRI has also boomed on the assumption that mainstreaming is taking place. However, little thinking has been carried out on questions specifically ar

General Introduction,called micro-skiagraphs of alloys, and although with the magnifications used at that time one can hardly speak of microscopy, they laid the foundation for contact microradiography to be developed later on. The refraction of X-rays in matter was not perceptible with the apparatus available at that ti

Properties and Limitations of the Projection X-Ray Microscope,had acquainted himself with their difficulties, which concerned mainly the small intensity, and proposed the use of a stronger lens. Impressed by the results Cosslett and Nixon demonstrated later at St. Andrews, and convinced that with appropriate dimensioning a considerable improvement could be exp

A New Focusing AID,hod was sought in the course of the work. The difficulty of the conventional method is mainly due to the low intensity combined with a low contrast of the image. Consequently the object under examination is generally unsuitable for focusing purposes. For this reason a more suitable fine mesh grid is

Contrast Improvement by the Use of Ultra Fine Grain Film,t applied to the projection method is the necessity of subsequent magnification with the aid of an optical microscope. Besides this requiring an extra action, the photographs obtained are rather small. Furthermore it is generally assumed that this kind of film has no particular advantages.

A Commercial Projection Microscope,eliable microscope which would be continuously available for studying the application possibilities was felt. Early in 1958 the design of such a microscope was started. When in November of that year the State University of Ghent gave an order for the building of a similar apparatus, it was decided t
