Abstract
The influence of annealing time on thermally stimulated discharge current of negatively and positively corona-charged Tefzel has been studied. For negatively charged samples the peak position and temperature are strongly dependent on annealing time. The TSDC spectrum for short annealing time is more complex than that for long annealing time. If the annealing time is long enough, the peak remains in the same position and it corresponds to the deeper energy level for traps, the traps being distributed exponentially in energy. The stored charge decays exponentially in time and the relaxation time is longer than the Maxwell relaxation time. The activation energy increases as the annealing time increases. For positively corona-charged Tefzel the peak positions do not depend on the annealing time. The stored charge decays fast. The activation energy for positively coronacharged samples is higher than that for negatively corona-charged samples.
