   Aug 7, 2023 · The new plasma source utilizes a 38 cm diameter lanthanum hexaboride (LaB 6) cathode, which has a significantly higher emissivity, allowing for a much larger discharge power density, and is robust to exposure to air. Peak plasma density of up to 3.0 × 10 13 cm −33 in helium gas has been achieved.
