In this chapter we shall consider: 1) basic physics controlling temperature in a superconducting winding; and 2) stability evaluation methods to quantify the likelihood of an unscheduled temperature rise within the winding. CHAPTERS 7 and 8 also deal with temperature rise in the winding under different contexts: CHAPTER 7 on causes or sources of temperature rises; and CHAPTER 8 on methods to protect magnets subsequent to unscheduled temperature rises. First, there is a striking difference in this stability issue between LTS and HTS magnets
