The calorimeter is used as a means of reducing the background in the charged particle measurements and searches by providing confirming measurements of the position, time of flight and energy. Since the calorimeter can measure both time of flight (velocity) and energy it provides an independent measurement of mass. The mass resolution of charged particles is much more precisely determined with the tracking system than with the calorimeter. For neutral particles, the calorimeter provides the only measurement. The tracking system is used only to verify that the observed energy did not come from charged particles.
Below we will discuss the simulations and analysis we have carried out to calculate the efficiency of the calorimeter for detecting interesting states and also the rejection power of the calorimeter for background processes.
