飞行中分离器的重要作用是从飞行中裂变和射弹碎裂产生的数千束放射性同位素中分离出一束特定的放射性同位素。然而，当从不同的观点看“分离”时，超过99%的同时产生的RI光束只是在焦平面狭缝或分离器的其他地方被消除。为了提高RIKEN飞行分离器BigRIPS的有效可用性，我们一直在开发一种创新方法：寄生激光离子源（PALIS），该方法通过在BigRIPS实验中保存被淘汰的RI束来实现寄生低能RI束的产生。在本文中，我们提出了预期的好处和可行性的PALIS概念和结果的第一停止检查高能RI光束在气室。
An in-flight separator performs the important role of separating a single specific radioactive isotope (RI) beam from the thousands of RI beams produced by in-flight fission as well as projectile fragmentation. However, when looking at ``separation'' from a different viewpoint, more than 99% of simultaneously produced RI beams are just eliminated in the focal plane slits or elsewhere in the separator. In order to enhance the effective usability of the RIKEN in-flight separator BigRIPS, we have been developing an innovative method: parasitic laser ion source (PALIS), which implements parasitic low-energy RI beam production by saving eliminated RI beams during BigRIPS experiments. In this paper, we present the expected benefits and feasibility for the PALIS concept and the results of the first stopping examination for high-energy RI beams in the gas cell.
