Quenching gases for limited-streamer operation

Abstract

Charge spectra and efficiencies of the limited-streamer mode are presented as a function of quencher fraction and high voltage for several gas mixes. The goal was to find a working gas of low hydrocarbon content in order to relieve safety concerns about the flammability of the large gas volume contained in the hadron calorimeter of the OPAL detector at LEP. No suitable low-hydrocarbon quenching mix is found. The charge spectra from these quenchers develop secondary peaks and long tails as full efficiency is approached, leading to catastrophic breakdown near the onset of full efficiency.
