The one equips four wavelength dispersive spectrometers (WDS) and another does three WDS. Those electron microprobes were customized by the authors for improvement: stability, sensitivity, wavelength resolution etc. Two customized analyzing crystals were installed on the electron microprobe to achieve higher wavelength resolution than JEOL original system. The liquid nitrogen trap is installed to reduce surface contamination in quantitative electron probe microanalysis of ultra-light elements. Mineral grains are used for the standard materials of chemical compositions and X-ray interferences to avoid introduction of nuclear fuel material to the Center for Chronological research. Calibration of standard materials is periodically performed in Korea Institute of Geoscience and Mineral Resources (South Korea) using well characterized standard materials., 第23回名古屋大学年代測定総合研究センターシンポジウム平成22(2010)年度報告}, pages = {44--48}, title = {CHIMEの現状と稼働状況 (2010年)}, volume = {22}, year = {2011} }
