在伊瓦斯基拉大学的IGISOL设施中安装了一个用于等压束净化的潘宁阱。在本文中，这种新设备的技术细节，以及第一次测试的结果。的质量分辨能力，取决于激发参数和离子种类，可以高达145 000和总传输已被确定为17%。此外，它示出，与此实验设置，它是可能的测量原子质量高达A = 120的精度约为50千电子伏。(C)2004 Elsevier B.V.保留所有权利。
A Penning trap has been installed for isobaric beam purification at the IGISOL-facility at the University of Jyvaskyla. In this paper, the technical details of this new device together with results of the first tests are presented. The mass resolving power, depending on the excitation parameters and the ion species, can be as high as 145 000 and the total transmission has been determined to be 17%. In addition, it is shown that with this experimental setup it is possible to measure atomic masses up to A = 120 with accuracies of approximately 50 keV. (C) 2004 Elsevier B.V. All rights reserved.
