Title: Guy Moiroud: Innovator in Photocathode Technology
Introduction
Guy Moiroud is a notable inventor based in Paris, France. He has made significant contributions to the field of photocathode technology, holding a total of five patents. His work focuses on advancements that enhance the efficiency and functionality of photocathodes.
Latest Patents
One of his latest patents is titled "Photocathode having internal amplification." This invention features a first electrode designed to receive a first voltage and transmit incoming photons. An absorption layer, made of P-type semiconductor material, is positioned adjacent to the first electrode. This layer converts incoming photons into electron-hole pairs. Additionally, the invention includes an ionization-induced electron multiplication layer, which consists of two layers of N-type semiconductor material with different compositions. This design allows for the acceleration of electrons more effectively than holes. The second electrode, placed next to the multiplication layer, receives a second voltage and transmits the accelerated electrons into a vacuum through an emission layer that produces negative electron affinity.
Another significant patent by Moiroud is the "Multilinear charge transfer array." This invention comprises N lines of P photosensitive detectors, each connected directly to a demultiplexing and reading system. The signals from the array are processed externally, and the demultiplexing system features a charge transfer shift register with N times P stages. The connections ensure that detectors of the same rank are linked to contiguous inputs, enhancing the efficiency of signal processing.
