Abstract :
The response of a sampling tile electromagnetic calorimeter was simulated for incident electrons in the 10–500 GeV energy range. The influence of tile to tile nonuniformity on the a and b coefficients of the calorimeter energy resolution parametrisation formula was investigated in detail. An energy resolution deterioration due to nonuniformity was observed, but it was shown that by calibrating the towers individually one can reduce this undesirable effect to reasonable limits. An explicit a and b coefficients dependence on σnon, the tile response nonuniformity standard deviation, was found. Our previous results on this dependence obtained by analytical methods using the electromagnetic shower mean profile universal parametrisation and the present results obtained by Monte Carlo simulation are compared and found to be in good agreement.
