本文介绍了一种基于一次离子束碎裂原理的多离子束的设计原理。这一过程预计将提供与入射束相同的每个核子动量的次级粒子，以及束中核元素的可变范围，对于任何重离子（Z > 50）初级束，对于一个特定的输运线设置，电荷Z的最宽分布从Z = 1延伸到Z 40-50，平均具有可比的单个速率。报道了在CERN的20 GeV/c核子铅原离子次级束中的应用。对测量结果进行了讨论。
The design principle of a multi-ion beam for instrumental tests, based on the fragmentation of a primary ion beam, is described. This process is expected to provide secondaries with the same momentum per nucleon as the incident beam, and a variable range of nuclear elements in the beam, with the broadest distribution of charge Z extending for one particular setting of the transport line from Z = 1 up to Z 40-50 at most, with comparable individual rates on the average, for any heavy ion (Z > 50) primary beam. The application in a secondary beam obtained from a 20 GeV/c per nucleon primary Pb ions at CERN is reported. The measured results are discussed.
