Design and Calculations for the New ECRIS at KVI

In this paper a brief description is given of the on‐going upgrade of the CAPRICE‐type ECRIS injector of the K=600 AGOR cyclotron at KVI. This upgrade is motivated by the new TRIμP program, which requires a significant increase of available beam intensity by up to two orders in magnitude. The upgrade follows the AECR design of the university of Jyvaskyla, which was originally pioneered at LBNL (USA). We will discuss the mechanical design and magnetic field calculations of the solenoidal and the permanent magnetic hexapole fields.
