Responsibilities/Job Description

For the update of the Swiss Light Source SLS at PSI, it is planned to use magnets based on permanent magnet materials. To counter the effect of temperature dependency, materials with temperature dependent permeability can be used to either enhance or reduce the effective field of a magnet. With the right design, such a material can cancel the temperature dependency of permanent magnet materials over the operating temperature range in a particle accelerator such as SLS. In the design process of such magnet systems, it is crucial to have reliable temperature dependent material data on hand.Therefore the topic of this master thesis is the design, construction and evaluation of a measurement system for determining the magnetic permeability of material samples at different temperatures.During the course of this thesis, a standard “Epstein Frame” should be constructed (DIN EN 60404-2:2009-01), but with the capability of being used in a range of temperatures between 4K and 400K. This requires the selection of suited materials as well as adjustments to the measurement technique and thermal control of the material samples during a measurement.The outcome of the proposed measurement setup should be verified versus other measurement techniques, e.g. a vibrating-sample magnetometer (VSM).
