THE ECR ION-SOURCE DECRIS

The design of the electron cyclotron resonance (ECR) multicharged ion source DECRIS (Dubna ECR ion source, 14 GHz) was started at the Flerov Laboratory of Nuclear Reactions at the beginning of 1990 and in Janua ry 1992 the first plasma was ignited. A classical magnetic configurati on based on the MINIMAFIOS with some ''features'' served as the basis for the source design. The DECRIS was installed on the ECR test bench. The first study of the source was carried out in continuous mode of o peration at strict control of hexapole temperature. The ion source has been tested with He, N, O, and Ar ions. The results of these initial measurements are presented.
