Development of system and technology for mössbauer spectroscopic microscope

We have been developing a “Mossbauer Spectroscopic Microscope (MSM)” which consists of a focusing lens for 14.4 keV γ-rays and a high precision X–Y stage. The measuring system both for electrons and γ-rays combined with a new Mossbauer driver, i.e., “a moving coil actuator with a liner encoder” enables us to measure the mapping images simultaneously corresponding to different spectral components. The system has a controlling system based on a LabVIEW program and a LIST mode data acquisition system (NIKI-GLASS/A3100). To investigate a correlation between the microstructure of a sample and 57Fe atoms, a scanning electron microscope (APCO/Mini-EOC) is also installed to this system.
