Opis:: The ECR laboratory of the Cyclotron Centrum of Slovak Republic (CC SR) in Bratislava, Slovakia, consists of the DECRIS 14-2m ion source and two low energy channels. It is a complete injector, consisting of an ECR ion source, focusing and steering elements, an analyzing magnet, a vacuum system, and an ion beam diagnostic system. The DECRIS 14-2m ion source is a multiply charged heavy ion source based on the electron cyclotron resonance principle. The ECR ion source DECRIS 14-2m and other system have been designed and manufactured at the FLNR JINR. The preliminary testing (magnetic field measurements, vacuum testing and testing of ECR ion source) has been performed at FLNR JINR. The final assembly of the DECRIS 14-2m will be done at the CC SR in Bratislava.

Opis:: A new JYFL 14 GHz ECRIS was completed in spring 2000 for the nuclear physics program at the Department of Physics, University of Jyväskylä (JYFL). The old JYFL 6.4 GHz ECRIS (built in 1990-1991) is now also available for the material physics experiments and for the research and development work of the ECR ion sources. During the last year remarkable modifications to the structure of the source have been undertaken. In the first phase, which was completed in fall 2001, the axial magnetic field was optimized using the old power supplies and the coils. The radial magnetic field was improved in spring 2002 by installing an iron cylinder around the hexapole permanent magnets. According to the measurements the improvement of about 25% to the radial magnetic field was achieved. The research work to improve the ion beam quality has been started.

Opis:: ECR ion sources are used for the production of highly charged ions in various accelerator facilities. In most of them biased electrodes are normally used to increase the ion yield. Physical processes in the plasma of an ion source are quite complicated and the role of a biased electrode is not clear. To investigate the effect of a biased electrode on the intensity of extracted highly charged ions, an axially movable electrode was placed into the plasma chamber of the DECRIS 14-3 ion source. It was found that the intensity of Ar ions depends on the position of the biased electrode and negative bias voltage. The optimal position of the biased electrode was found near the maximum of the magnetic field. Experiments with a pulsed biased electrode were also carried out. The influence of the negative pulse on the ion yield depends on the ion charge state.
