METAL ION BEAMS PRODUCTION AT ECR-SOURCE “DECRIS-3” WITH SOLID STATES HEATING TECHNIQUE

Accelerated beams of metal ions are required for a series of scientific and technical tasks in the field of radiation physics of a solid state, for example, the only method for rapid assessments of the radiation damage investigation, the developed structural materials of nuclear technology is ion irradiation. The standard methods for production ion beams at ECR-sources from gas mixtures cannot fully meet the requirements of the experiment. To increase the spectrum of accelerated ions at the cyclotron DC-60 is working on developing methods of heating the solid substances to produce multiply charged ion beams of metals into an ECR ion source DECRIS-3. The article is dedicated to description of methods of production ion beams of metals in two ways: the direct injection of a substance into plasma and a method of heating the crucible with a working substance by micro-furnace. As a result of the work carried out on the DC-60 cyclotron, beams of lithium ions ^6,7Li, ²⁴Mg magnesium, ³¹P phosphorus and ⁴⁰Са calcium were produced for the first time. Using these methods was produced beams of lithium ions ⁷Li¹⁺ metal consumption of 1.1 mg/hour and derived a ion beam current of 500 µA, magnesium ²⁴Mg⁴⁺ with the consumption of the substance 2.1 mg/hour and intensity of 81 µA, phosphorus consumption of substances 1.7 mg/hour at the beam current ³¹P⁵⁺ 60 µA and calcium ⁴⁰Ca⁵⁺ with the consumption of a substance of 0.7 mg/hour when the beam current is 140 µA.
