Abstract
The ion temperature gradient (ITG) driven instability is investigated for a plasma with trapped ions and collisions. For the toroidal branch , the perpendicular temperature gradient is needed for the instability in contrast to the slab branch. The threshold value of the temperatur e gradient is higher with trapped ions and is further increased by ele ctron and ion collisions. A theoretical model is used to explain the e xperimental results for a hybrid trapped ion ITG mode in the Columbia linear machine.
