Photomultiplier tube with one dynode insensitive to high magnetic fields
Description
This tube includes a photocathode deposited on a transparent window at the end of an insulating sleeve tube, the photocathode is carried to a reference potential V0. This tube includes an unique amplifier stage constituted by a dynode; its shape is a metallic surface one leaning on a contour surrounding sensitively the photocathode and bearing on its inner face a secondary emission material coating; an anode, constituted by a metallic grid homeomorphic to the dynode surface, is set parallel to and at a little distance of this one. The dynode and the anode are carried respectively to an electric potential V1 higher than the reference potential V0 and at an electric potential V2 higher than the dynode potential V1. This tubes can be used in particle accelerators, in nuclear physics

Ce tube comporte une photocathode deposee sur une fenetre transparente a l'extremite d'un manchon isolant; la photocathode est portee a un potentiel V0 de reference. Ce tube comporte un etage amplificateur unique constitue par une dynode, de la forme d'une surface metallique s'appuyant sur un contour entourant sensiblement la photocathode et portant sur sa face interne une couche d'un materiau a emission secondaire; une anode formee par une grille metallique homeomorphe a la surface de la dynode est placee parallelement et a faible distance de celle-ci. La dynode et l'anode sont portees respectivement a un potentiel electrique V1 superieur au potentiel V0 de reference et a un potentiel electrique V2 superieur au potentiel V1 de la dynode. Ces tubes sont applicables en physique nucleaire, dans les accelerateurs de particulesAdditional details
