ENHANCEMENT OF XRF INTENSITY BY USING Au COATED GLASS-CAPILLARY
نویسندگان
چکیده
Enhancement of XRF intensity was investigated by using an Au coated glass-capillary. Au was electroplated on an inner wall of the glass-capillary with a thickness of 100 nm. The Au coated glass-capillary was attached to a micro focus x-ray tube. The XRF intensity from the pure metal samples was measured by a silicon drift x-ray detector. It was confirmed that the intensity of XRF was enhanced by using Au coated glass-capillary by factors of 1.1 to 1.5 times. The XRF intensity profile was also measured by wire scanning method to investigate the reason. The trace of primary x-ray beams was calculated considering x-ray total reflection. The calculated results of agreed well with the experimental XRF intensity profile. The reason of enhancement XRF intensity was that the primary x-rays were totally reflected on the inner wall of
