Das Konvergenz‐Verfahren, ein hocheffektives Verfahren zur röntgenographischen Untersuchung von Kristallen (Konvergenz‐Kamera)

In taking a convergence beam photograph a stationary crystal is lightened by the line focus of an X‐ray tube. This experimental arrangement ensures that for a number of sets of net planes the Bragg condition is fulfilled simultaneously and during the full time of exposure especially for the intense characteristic line of the X‐ray spectrum applied. Due to this effect the application of the convergence method yields extremely short exposure times compared to other usual X‐ray film methods. A convergence camera may be constructed very simple (not any electrical equipment). It is a very useful tool in X‐ray crystallography.
