CMS Level-1 Calorimeter Trigger Detailed Simulation

CMS level-1 calorimeter trigger simulation results are discussed. The simulation results are obtained using CMSIM version 111 program based on the GEANT simulation of the detector. These CMSIM results compare favorably to the results from our fast simulation program used in earlier studies. Both these results indicate that the rate requirements of the data acquisition system can be met with a reasonable safety factor of three while providing high efficiencies for high ET physics processes of interest to CMS.
