Design and evaluate a compact Penning ion source with a minimal discharge volume operating under both continuous and pulsed discharge modes.
Fabricated a compact source with a 1.24 cm³ discharge volume using two concentric cylindrical cathodes of differing heights and a single hollow cylindrical anode.
Optimized internal geometry to produce a homogeneous magnetic field and integrated an axial extraction system with variable extraction voltage across different gas environments.
Generated dense plasma at low discharge power, recording discharge current pulses of hundreds of amperes characterized by low delay times and fast rise times.
Achieved an extracted ion beam current of 200 µA in continuous mode and a 6 A fast pulse in pulsed discharge mode across a wide range of low pressures.
