Limitations of the Hecht Equation Encountered in Measuring mu tau Products in Mercuric Iodide
Abstract
While attempting to measure (mu)t products in HgI2 using the pulse rise time method a method based on the Hecht equation fundamental limitations of the Hecht equation were revealed These limitations restrict the equations utility even for the case for which it was originally developed, i.e. when carrier trapping occurs without de-trapping. The Hecht equation purportedly analytically characterizes the charge collection process under uniform field and permanent charged carrier trapping conditions Since de-trapping occurs in HeI2 particularly in high spectral performance HgI2 detectors it was recognized that limitations would be encountered in applying the Hecht equation.
