The magnetic field forms the magnetron configuration of the discharge and provides a radial electric insulation. The source typically operates with a discharge current of up to 350 A in hydrogen. Plasma parameters in the SMOLA device are Ti ∼ 5 eV, Te ∼ 5-40 eV and ni ∼ (0.1-1) × 1019 m-3. Helium plasma can also be created.
