The one equips four wavelength dispersive spectrometers (WDS) and the other does three WDS. Those EMP equipments were customized by the authors for improvement: stability, sensitivity, wavelength resolution etc. Two customized analyzing crystals were installed on the EMP to improve wavelength resolution. The liquid nitrogen trap (cold trap) was installed to reduce surface contamination. The integrated machine time was about 2.500 hours for the CHIME dating in 2009. The total number of analysis points was over 40,0OO excluding 2-dimensional mapping., 第22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21(2009)年度報告}, pages = {25--30}, title = {CHIMEの現状と稼働状況(2009年)}, volume = {21}, year = {2010} }
