We have carried out a series of measurements demonstrating the feasibility of using the Dresden electron beam ion source (EBIS)-A, a table-top sized, permanent magnet technology based electron beam ion source, as a charge breeder. Low charged gold ions from an AuGe liquid metal alloy ion source were injected into the EBIS and re-extracted as highly charged ions, thereby producing charge states as high as Au(60 +). The setup, the charge breeding technique, breeding efficiencies as well as acceptance and emittance studies are presented.
我们进行了一系列测量，证明了使用德累斯顿电子束离子源（EBIS）-A作为电荷增殖器的可行性。EBIS-A是一种桌面尺寸、基于永磁技术的电子束离子源。来自金锗液态金属合金离子源的低电荷金离子被注入到EBIS中，并作为高电荷离子重新引出，从而产生高达Au(60 +)的电荷态。本文介绍了该装置、电荷增殖技术、增殖效率以及接受度和发射度研究。
