ATLAS设施的Cariu升级为低能和库仑势垒能量的实验提供了富含中子的放射性束流。它使用一个大型的射频气体捕集器来创建这些光束，该气体捕集器收集并冷却来自强烈的CF-252裂变源的裂变碎片，并将它们转换成低发射率的单能光束。然后，这种光束可以被提纯、再加速，然后送到实验中去。这项技术是快速和通用的，提供了对所有裂变碎片物种的访问，而不依赖于它们的化学性质。Cariu气体捕集器被建造成在高电离密度下运行，并在污染源存在的情况下运行。下面简要概述了Cariu的概念，并对Cariu气体捕集器及其目前所取得的性能进行了更详细的说明。爱思唯尔出版公司(Elsevier B.V.)
The CARIBU upgrade of the ATLAS facility provides radioactive beams of neutron-rich isotopes for experiments at low and Coulomb barrier energies. It creates these beam using a large RF gas catcher that collects and cools fission fragments from an intense Cf-252 fission source and transforms them into a low-emittance monoenergetic beam. This beam can then be purified, reaccelerated and delivered to experiments. This technique is fast and universal, providing access to all fission fragment species independently of their chemical properties. The CARIBU gas catcher has been built to operate at high ionization density and in the presence of the contamination from the source. A brief overview of the CARIBU concept is given below, together with a more detailed description of the CARIBU gas catcher and the performance it has now achieved. Published by Elsevier B.V.
