Progress report on the mVINIS ion source

The mVINIS ion source is one of the major machines of the TESLA Accelerator Installation, at the Vinca Institute of Nuclear Sciences. It is an electro n cyclotron resonance ion source with multiple applications. It can serve a s an injector for an isochronous cyclotron providing heavy ions for several high energy experimental channels (radiation physics, radiation biology, p hysics of thin crystals, nuclear physics) or as a stand alone machine direc tly delivering multiply charged ions to the low energy experimental channel s (physics of multiply charged ions, surface physics, surface modification of materials). This article describes the completion of mVINIS that include d the finalization of its safety and control systems, the fine adjusting an d calibration of its gas inlet system, and the installation of the solid su bstance inlet system. The recent results obtained with ion beams produced f rom 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. (C) 2000 American Ins titute of Physics. [S0034-6748(00)63002-2].
