We have now extended this method for preparing thorium dioxide (ThO2) targets. This is significant for nuclear energy research since there is a renewed interest in ThO2 as an alternative to the traditional uranium based nuclear fuel and ThO2 thin targets are more convenient than fuel pellets for studying its characteristics. Precise control of the thicknesses and high uniformity of the ThO2 targets prepared using this method are verified with multiple surface characterization methods: scanning electron microscopy, X-ray fluorescence spectroscopy and alpha-spectroscopy. This talk summarizes the development of the ThO2 target preparation method using spin coating assisted combustion method.
