High voltage test bench for heavy ion beam probe diagnostics on T-15MD tokamak
D-shaped tokamak T-15MD is nowunder construction in the NRC “Kurchatov Institute”. Heavy ion beam probing (HIBP) is an important part of T-15MD diagnostic system. Calculations of the probing ions trajectories show that the beam will pass through the plasma about 1.0…1.5 m, which can lead to its sign...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | D-shaped tokamak T-15MD is nowunder construction in the NRC “Kurchatov Institute”. Heavy ion beam probing (HIBP) is an important part of T-15MD diagnostic system. Calculations of the probing ions trajectories show that the beam will pass through the plasma about 1.0…1.5 m, which can lead to its significant attenuation. HIBP operation requires obtaininga high-current long-focus probing beam of Tl+ ions (I = 200…400 μA, f = 4…6 m, d ≤ 10 mm). A high voltage (300 keV) test-benchto test such beams is eing created now. Numerical modeling shows the possibility of a beam formation with a current of 300 μA and diameter 12 mm at 6 m from the ion emitter. |
