Progress report on the mVINIS ion source

The mVINIS ion source is one of the major machines of the TESLA Accelerator Installation, at the Vinča Institute of Nuclear Sciences. It is an electron cyclotron resonance ion source with multiple applications. It can serve as an injector for an isochronous cyclotron providing heavy ions for several high energy experimental channels (radiation physics, radiation biology, physics of thin crystals, nuclear physics) or as a stand alone machine directly delivering multiply charged ions to the low energy experimental channels (physics of multiply charged ions, surface physics, surface modification of materials). This article describes the completion of mVINIS that included the finalization of its safety and control systems, the fine adjusting and calibration of its gas inlet system, and the installation of the solid substance inlet system. The recent results obtained with ion beams produced from gases and solid substances are presented, showing the wide capabilities of this machine. The ion beams obtained from mVINIS have been used in the channel for modification of materials since May 1998.
