Title: The Innovations of Noel Santonja
Introduction
Noel Santonja is a notable inventor based in Créteil, France. He has made significant contributions to the field of electron technology, holding a total of three patents. His work focuses on enhancing the efficiency and performance of electron guns and travelling-wave tubes.
Latest Patents
One of his latest patents is for an electron gun with reduced heating of the grid. This innovative design features a cathode made of an emissive material with an active face that emits electrons through a control grid positioned before the active face without direct contact. The active face includes both emissive and non-emissive zones, with the latter formed by grooves hollowed out of the emissive material. The control grid is designed with solid parts that directly face these grooves, which helps in reducing the heating of the control grid.
Another significant patent involves a travelling-wave tube equipped with a brazed T-shaped helix delay line. This design includes a helix mounted in a metal sleeve, centered by at least three dielectric rods. The helix is constructed from a thin strip of metal that is an excellent conductor of heat and electricity. The T-shaped cross-section of the helix, particularly at the points of contact with the rods, prevents the risk of electric arcs at the brazing beads on consecutive turns of the helix. This advancement is applicable to travelling-wave tubes that operate over wide bandwidths and at high power levels.
