title = "Calibration of Faraday cup efficiency in a multicollector mass spectrometer",
abstract = "Faraday cup efficiencies (FCE's) in the multicollector mass spectrometer were examined with a static multicollcction technique. The relative Faraday cup efficiency (RFCE) was estimated by measurement of Nd-isotopc ratios with five different cup configurations. The application of RFCE correction to the static multicollection technique will increase the reliability of analytical results by eliminating the errors caused by differences in FCE's, and will also enable us to distinguish which Faraday cups are damaged and should be renewed.",

note = "Funding Information: We are very thankful to S. Akimoto, H. Honma, H. Kagami and K. Nagao (ISEI) for supporting this work. We owe a great deal to the discussion with the Finnigan-MAT engineer, H.I. Kiihn, who visited Misasa to repair our mass spectrometer. We acknowledge B.M. Jahn for discussionsc oncerning the problem of the cup damage in multicollector mass spectrometer. We are also very grateful to A. Ma-suda and H. Shimizu (The University of Tokyo) for offering the La Jolla Nd standard. Our thanks are extended to R. Hill (Australian National University) for brushing up our English. This research was supported by Mon-busho (Ministry of Education, Science and Culture, Japan) International Scientific Research Program and by a Grant-in-Aid for Scientific Researchf rom Monbusho.",
