Design and construction of focusing lens to be applied to the XRF analysis. Final report for the period 1 December 1993 - 30 November 1995

摘要

The construction and performance test for assembled and monolithic lenses have been done. Experimental setups and procedures for the determination of focussing capability of the lenses (diameter of the X-ray beam), beam profile at the focal plane, and transmission efficiency were designed and provided the necessary data. The results of the test of both lenses (assembled and monolithic) are good. The fact that the monolithic lens is significantly better as far as the spot size and gain factor are concerned, proves the advantages of the new technology for production of focussing optics for XRF analysis. The spot size of X-ray microbeam (200 micrometers) is adequate for many applications of XRF technique for trace element determination with both advantageous detection limits and imaging capability.
