Mossbauer gamma-ray size focused using MCX measured by Si-PIN semi-conductor detector

Abstract

In the 2014 General Meeting of Mineralogical Society of Japan, we reported focus size of 14.4keV g-ray of Mössbauer microspectorometer using a multi-capillary X-ray lens (MCX) and proportional counter detector.  In that report, a proportional counter was used as γ-ray detector.  In this report, a Si-PIN semi-conductor, of which energy resolution is better than a proportional counter, is used to fix the spot size of focused g -ray by MCX.
