SIMDET—a parametric Monte Carlo for a TESLA detector

We briefly describe the principles of operation of the program package SIMDET, a parametric Monte Carlo program to simulate the response of a detector for the TESLA linear collider. Main detector components are implemented according to the TESLA Conceptual Design report, with a tracking system, an electromagnetic and a hadronic calorimeter, a vertex and a luminosity detector. Using the results from the ab initio Monte Carlo program BRAHMS, track parameters and calorimetric deposits are treated in a realistic way. Pattern recognition is emulated using cross references between generated particles and detector response. An energy flow algorithm defines the output of the program. Further improvements and completions of SIMDET are also discussed.
