初级束流收集器是ISOL靶室系统的重要部件。它位于靶的后方,主要作用是对回旋加速器注入进靶室的剩余束流进行收集,并在靶被打穿的极端情况下,对束流进行收集以确保系统其他部件不受损害。收集器的基本结构示于图1。收集器采用高熔点的材料作为接受束流轰击的部分,利用高导热性的铜基将热量传递给水冷系统。中心区域采用锥面以增大束流的分布面积。 Primary beam collectors are an important part of the ISOL target chamber system. Located behind the target, the primary function is to collect the rest of the beam injected into the target chamber by the cyclotron and, at the extreme end of the target penetration, collect the beam to ensure that the rest of the system is not damaged. The basic structure of the collector is shown in FIG. The collector uses a high melting point material as part of the beam that receives the beam and uses the high thermal conductivity of the copper-based heat transfer to the water-cooled system. The center area uses a tapered surface to increase the distribution area of ​​the beam.
