Title: Albert Edward Berwick: Innovator in Electron Tube Technology
Introduction
Albert Edward Berwick is a notable inventor based in San Jose, CA. He has made significant contributions to the field of electron tube technology, holding a total of 2 patents. His work focuses on enhancing the performance and efficiency of high-power linear-beam electron tubes.
Latest Patents
One of Berwick's latest patents is for a "Permanent magnet structure for linear-beam electron tubes." This invention addresses the challenges posed by leakage fields that can damage the tube's collector. By utilizing an axially magnetized energizing magnet at the collector end and a radially magnetized magnet at the cathode end, Berwick effectively reduces the leakage field. Additionally, he proposes the use of a shield around the outside of the cooling fins to further protect the collector.
Another significant patent is the "Dual mode gridded gun." This invention allows travelling wave tubes to operate interchangeably at low power continuous wave (cw) and high pulsed power. The design includes grids that gate pulses and switch the peak beam current between two values. To maintain optimal beam-focus conditions, the beam diameter is adjusted simultaneously. The cathode features a hyperboloid of revolution shape, which provides the necessary ratio of beam sizes and uniform loading.
