Heavy ion accelerator (UTI-2)

The design and test results of the 2 MeV ion accelerator designed for science of materials are described. The UTI-2 accelerator is developed on the basis of the UTI-1 accelerator and equipped with an injector of five-charge ions of iron, chromium and other elements with beam intensity of 50-100 μA, source electromagnet, mass-separator, accelerating system, target complex, a system for doping materials and powders of different metals and alloys. The test results pointed out that metal ion beams with 4-6 charge degree and intensity up to 100 μA may be obtained by means of a plasma-arc source operating in a continuous mode. Metal ions in the total beam current makes up 55-85 %. Yield of multicharge ions grows with increase of magnetic field strength and power introduced into the charge. Beam emittance of multicharge ions does not exceed 40 cmxmrad. The UTI-2 accelerator may be used both for studies on physical radiation damages and works on semiconductor ion doping
