摘要： Thin flexible sheets of high-permeability FINEMET® foils encased in thin plastic layers have been used to shield various types of 20-cm-diameter photomultiplier tubes from ambient magnetic fields. In the presence of the Earth's magnetic field this type of shielding is shown to increase the collection efficiency of photoelectrons and can improve the uniformity of response of these photomultiplier tubes. 出版者： Elsevier B.V 出版日期： 2014-02-11 出處： Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2014-02, Vol.737, p.222-228 版權： 2013 Elsevier B.V. 識別號： ISSN: 0168-9002 識別號： EISSN: 1872-9576 識別號： DOI: 10.1016/j.nima.2013.11.024
