description

Abstract For liquid argon calorimeters electronegative impurities dissolved in the medium degrade the detector response and deteriorate the energy resolution, especially at high energies. A concept for a purity monitoring system for liquid argon calorimeters has been developed and is presented here. Special combined monitors of 241 Am- and 207 Bi-cells are used to monitor the concentration of impurities. The working principle as well as results from test measurements are discussed.
