This paper discusses the design of the quench protection for a conduction-cooled MgB2 magnet system that will be used for magnetic density separation (MDS). First, an extensive literature review is made of currently available quench detection and - protection methods, which are discussed in a structured way in terms of merrits and challenges. Next, the measured normal zone propagation velocity and minimum quench energy of MgB2 wire produced by Columbus SpA are reported and used as input for pseudo-analytical modeling of the maximum hotspot temperature and coil voltages. These simulated quench characteristics are then combined with the literature review to select the most adequate quench detection and - protection strategies.
The work is part of the research programme “Innovative Magnetic Density Separation for the optimal use of resources and energy“ with project number P14-07, which is (partly) financed by the Netherlands Organisation for Scientific Research (NWO).
