Description
In recent years, the need for replacing the materials for the construction of several accelerator components has arisen from the framework of the high-luminosity upgrade for the Large Hadron Collider (HL-LHC). To address this, new materials have been considered, and a proper characterization of their magnetic properties has become essential. This poster describes the magnetic measurement procedure and presents the reference method adopted at the Magnetic Measurement Section, a standard fluxmetric method based on a split-coil permeameter. In particular, the magnetic characterization of three materials is reported: ARMCO, for the construction of the yokes of new magnets; and CRIOPHY, for the magnetic shield of the crab cavities (CC), and feebly magnetic materials, such as austenitic stain steel, to validate the use of the same inductive method for their magnetic characterization.
