Abstract
1436871 X-ray collimators R D ALBERT 4 May 1973 [8 May 1972 24 April 1973] 21428/73 Heading H5R [Also in Division G1] A collimator is provided in an X-ray fluorescence spectrometer (see Division G1) between primary targets 54 and secondary targets 61, 62, the collimator comprising dense material 57 having apertures 58 therethrough and having a coating 58 of beryllium or other low atomic number material to reduce the the emission of characteristic X-rays from material 57. Divisional applications 38432/75 and 51070/75 have descriptions substantially identical to the present Specifications.
