Title: Jean-Marie Deon: Innovator in X-ray Technology

Introduction

Jean-Marie Deon is a notable inventor based in Grenoble, France. He has made significant contributions to the field of X-ray technology, holding a total of 2 patents. His work focuses on improving the functionality and efficiency of X-ray image intensifier tubes.

Latest Patents

One of his latest patents is a method for the use of an X-ray image intensifier tube. This invention involves a succession of electrodes, including a photocathode. The method allows the X-ray image intensifier tube to alternate between an off state and an operating state. It consists of applying an operating voltage that is substantially zero when in the operating state and a positive turning-off voltage greater than the operating voltage when in the off state. This innovation is particularly applicable to X-ray image intensifier tubes used in systems that operate alternately.

Another significant patent by Deon is an image intensifier tube with optimized electrical insulation. This apparatus focuses on electrically insulating viewing windows in an image intensifier tube. The mechanical parts near the window are insulated, with metal parts held at high voltage and protected by an insulating screen. This screen includes both an electrically conductive layer and an insulating layer, which separates the metal parts from the conductive layer. The conductive layer creates an equipotential layer that stabilizes the distribution of electrical lines of force within the insulating screen.
