Study of the magnetic characteristics of ferrites with a view to their application in a proton synchrotron; Etudes des caracteristiques magnetiques des ferrites en vue de leur application dans un synchrotron a protons

Abstract

In this report magnetic properties of some Ni Zn ferrites available in France are investigated for the purpose of their use in accelerating cavities of proton synchrotron. An attempt is made to measure permeability and quality factor of ferrite versus various physical parameters such as frequency F, the induction B, the magnetic bias field Hp and the temperature, the investigation ranges being: F {<=} 40 Mc/s; B {<=} 10{sup -2} Tesla; Hp {<=} 5000 AT/m; T {<=} 100 C. The measurements were carried out with the one hand, conventional impedance bridge (Q-meter, RX-meter) and on the other hand, with resonating method using an inductive ferrite loaded cavity in parallel with an external capacity. The latter method is of particular interest for the measurements in function of induction and magnetic bias field.

On effectue les mesures d'une part a l'aide des ponts d'impedance classiques (Q-metre, RX-metre) et d'autre part par la methode du resonateur qui consiste a mettre en parallele une cavite inductive chargee de ferrite et une capacite exterieure. Cette derniere methode est particulierement interessante pour les mesures en fonction de l'induction et du champ magnetique polarisant. (auteur)}
