Latest Patents
One of his latest patents is for a cathode ray tube with an ion trap that includes a barrier member. This invention addresses the issue of positive ions generated in a vacuum tube that can negatively affect the electron emission of a cathode. The design features a plate that traps these ions while allowing the generated beam to pass through an aperture, ensuring minimal influence on beam intensity. Another significant patent involves an electron emission device equipped with a reservoir containing material. This invention aims to enhance the stability of a cold cathode by coupling a vacuum space with a reservoir that contains a source of material, such as caesium, which reduces the work function. By managing the vapor pressure and temperature within the reservoir, the device compensates for the loss of caesium at the emitting surface of the cathode.
