High Homogeneity Solenoidal Magnet for Cesium Frequency Standard

Abstract

In Cs frequency standards a zone of highly uniform magnetic flus density, lower in value of 0.1 T, is required The magnetic homogeneity value is tied to the overall accuracy of the standard and, for an accuracy of a design value 1 p.p.m. is required. For this purpose a resistive solenoid 700 mm long with a bore radius of 32.5 mm has been designed and built. This paper reports the design process, the measurements on the manufactured magnet and the shimming strategy used to reach the homogeneity target.
