Analysis on the Characteristic of the Beam Optics System of an On-line Isotope Separator
摘要
Abstract
The isotope separator used on-line is the most effective and powerful facility for systematically studying short-life nuclides which are far away from the line of beta stability. An introduction of the beam optics system of ISOLDE type with a 55o deflection of beam is presented in this paper. According to the factors affecting the mass resolving power of the an-alyzing magnet,the requirement of increasing the resolution of the system and reducing the loss of beam can be satisfied with the combination of quadruple doublets and einzellens. In addition,by calculating the mass resolving power of the analyzing magnet and the horizontal dimension of beam in different influence factors on the magnet of CARR ISOL,a conclusion can be drawn that the resolution of the system will be higher with better stability of the sup-ply powers,higher voltage for accelerating and smaller normalize beam emittances.关键词
