Abstract

The X-ray source based on parametric X-ray radiation (PXR) has been developed and employed for users studies at the Laboratory for Electron Beam Research and Application (LEBRA), Nihon University. The energy of the PXR beam is limited to 34 keV in the case of using Si(220) as a radiator. Samples made of heavy materials such as lanthanides are difficult to treat for element imaging based on K-shell absorption edges because of the upper limit of the X-ray energy. Therefore, we decided to introduce Si(400) crystals into the LEBRA-PXR source in order to provide a PXR beam above 40 keV for the investigation into protonic ceramic fuel cells (PCFC) containing Ce, La and Ba. The 40-keV PXR beam was successfully observed and the properties are in good agreement with the theoretical calculation of PXR. Although the X-ray yield obtained from Si(400) is relatively low, preliminary experiments on imaging for PCFC samples have been performed with long measurement times.

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
