为IBA C70回旋加速器设计研制的采用Cusp场型H~-离子源与产生He束的ECR离子源的双束轴向注入系统(英文)

摘要

At the moment,a 70MeV cyclotron is under construction by the IBA company.This cyclotron will be able to accelerate H- beam from a multicusp source and with a beam intensity in the range of 10mA at the source extraction.A He1+2+ beam is also required.This beam will be produced by a PANTECHNIK ECR ion source（SUPERNANOGAN）with an extracted current of 1 to 2mA.In this paper the studies and design of the two sources with a common axial injection in the cyclotron are described.
