Abstract

1,089,975. Diffraction apparatus. CHIRANA PRAHA NARODNI PODNIK. May 21, 1965 [May 23, 1964], No. 21584/65. Heading H5R. A diffraction goniometer is arranged to operate on both the central (Bragg-Brentano) and the tangential (Seemann-Bohlin) focusing principles. The apparatus includes a rotatable crystal or specimen at the central S 1 of focusing circle K 1 on the circumference of which is situated the focal point F of the X-ray source. The detector having a slit S, is mounted on a base-plate P movable along an arm R 1 , rotatable about the centre of circle K 1 . In operation on the central principle, the detector is located in one position on the arm R 1 , and travels along the circumference of circle K 1 as rotation of the crystal necessitates. The apparatus also includes an auxiliary arm R 2 rotatable about an axis at one end, this axis being on the circumference of circle K 1 and equidistant from the focal point F and the crystal axis S 1 . In operation under the tangential principle, the end of the arm R 2 , which travels round a further focusing circle K 2 , engages the detector baseplate and as it rotates, slides the detector along the arm R 1 so that the detector travels around circle K 2 rather than that K 1 . This causes the crystal to remain tangential to circle K 2 and the detector to move into the required positions on circle K 2 to receive rays from the crystal. The link between the drives for arms R 1 and R 2 is provided by means of helical gears (SK 1 and SK 2 ) which rotate about the centres of circles K 1 and K 2 , respectively and which in the tangential principle of operation can be connected by displacement of a worm drive (S n ) which then engages with the gear (SK 2 ) (Fig. 5, not shown). The invention has equal application with other radiations besides X-rays, e.g. γ- rays, neutrons.
