Weijian Zhou,Weijian Zhou,Feng Xian,J. Warren Beck,A. J. Timothy Jull,Zhisheng An,Zhenkun Wu,Min Liu,Maobai Chen,Alfred Priller,Walter Kutschera,George S. Burr,Huagui Yu,Shaohua Song,Peng Cheng,Xianghui Kong +15 more
TL;DR: In this article, a reconstruction of geomagnetic relative paleointensities for the past 130 kyr from 10Be records in 2 Chinese loess-paleosol sections using a correction based on the correlation of 10Be with magnetic susceptibility (SUS) to remove the climatic contamination.
Journal ArticleDOI

Weijian Zhou,Maobai Chen,Yuguang Liu,Douglas J. Donahue,J. Head,J. Head,Xiangshun Lu,A. J. T. Jull,Lin Deng +8 more
TL;DR: The first international minicyclotron AMS facility has been brought into routine operation after many years of eAort as discussed by the authors, and the mass resolution of this device is greater than 3000, and the precision of isotopic ratio measurements is 1%.
Journal ArticleDOI
Status of the sinr mini-cyclotron ams facility
Maobai Chen,Xiangshun Lu,Guosheng Chen,Senlin Xu,Ligong Shen,Deming Li,Yuexiang Zhang,Pairong Gong,Yingji Zhang,Weijian Zhou +9 more
TL;DR: In this article, a progress report for the SINR minicyclotron SMCAMS is given, where a home-made multi-sample device for the ion source has been extensively tested and the sequential acceleration of 12 C, 13 C and 14 C has been explored.
