16 September 1994 Importance of electron tracking in understanding the response of proportional counters
Author Affiliations +
Design, construction, and sensitivity estimates for the performance of proportional counters customarily neglect the consequences of the finite path length of electrons resulting from the primary interaction between the incident x-ray and the proportional counter gas. In many situations this can lead to errors in response functions as a result of ignoring 'charge sharing' between adjacent proportional counter cells which are held in anti-coincidence, or charge lost by the electrons escaping the gas volume into the detector window or into inactive regions. We illustrate the importance of these effects with Monte-Carlo simulations.
