[Studies and design of a dual beam axial injection system using H- cusp source and ECR ion source for He for IBA C70 cyclotron]

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 (SUPERNANOCAN) 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.
