Prospects for using photosensitive dopants to improve the e/π ratio of liquid argon calorimeters

Abstract

There is evidence that shows that heavily ionizing interactions contribute to the signal from hadrons in liquid argon calorimeters, and that saturation effects play an important role in the e/π ratio. Measurements and calculations are presented which indicate a substantial improvement can be made to the e/π ratio by the addition of a few ppm of photosensitive dopants.
