Latest Patents
One of Farrell's latest inventions is the "Wire Ion Plasma Gun." This cutting-edge device generates electron beams with exceptional dose uniformity, facilitating a variable dose application to materials during irradiation. The technology operates by accelerating positive ions through an extraction grid towards a high-voltage cold cathode, which, upon bombardment, releases secondary electrons to form a precise electron beam. Notably, the design ensures that the electron beam emerging through a foil window maintains a comparable area and uniform distribution to that of the impinging ion beam.
Another notable patent is the "Ion Plasma Electron Gun with Dose Rate Control via Amplitude Modulation." Similar in operation to the Wire Ion Plasma Gun, this invention also focuses on the production of large area electron beams characterized by uniform electron distribution. The innovation integrates a current control power supply and a comparison circuit, enabling consistent output of secondary electrons from the foil window, thereby enhancing the precision of the electron beam.
