Abstract

The characteristics of the prototype of the endcap hadron calorimeter for the CMS facility have been measured. Using the relations between the measured calorimeter response to a radiation source, muons, and pions, it is possible to determine the energy scale of the data-acquisition electronics, which will be used in future experiments along with the calorimeter. The light yield in the calorimeter due to a minimum-ionizing particle was measured. The effect of various factors on the duration of the calorimeter signal is analyzed. The joint operation of the hadron and electromagnetic calorimeters was investigated. The possibility of adjusting the uncompensated system using the data from a scintillation counter inserted between the calorimeters is analyzed. It is shown that the presence of a structural material between the calorimeters will not lead to a noticeable degradation in the energy resolution of the hadron calorimeter.
