Abstract

The degradation in the signal from sampling, noble liquid, ionization calorimeters due to charge buildup from the slowly drifting positive ions was calculated. The degradation of the signal was significant in calorimeters planned for operating at high luminosity hadron colliders. The results showed that for a forward calorimeter at a distance of 5 m from the interaction point, the relative ionization rate at EM shower maximum changes.
