Laue crystallographic orientation with a fixed detector

2019-12-06T07:39:48Z (GMT) by John S. Reid
Abstract A FORTRAN program is described that finds the orientation matrix appropriate for a single crystal mounted on a Eulerian cradle in a Laue scattering apparatus where there is a fixed narrow aperture detector or fixed reference direction in the scattering plane. The essence of the alignment strategy is that two or more Laue spots are directed successively towards the reference direction, missing it by measured amounts. The program also evaluates the Eulerian angles χ and φ necessary to make a gi...
