Brahms

A Monte Carlo Simulation for a Detector at a 500/800 GeV Linear Collider

Current release: 3.1.3

Project Description
An ECFA/DESY 1997 workshop series on the physics and detector requirements at a 500/800 GeV linear collider led to a Conceptual Design Report which summarizes the findings of the study and which forms the starting point for the GEANT description coded in the program Brahms. The detector concept has been further developed and is more fully described in the TESLA technical design report, published in 2001. Brahms is an implementation of the TDR detector. The detectors in V308 reflect the state of developments as of summer 2002.

Brahms is written in FORTRAN and uses GEANT3 and optionally writes LCIO-files. The aim was to produce quickly a working detailed detector simulation to provide a basis for future developments and to cross-check the assumptions made in the fast simulations used for physics.

The user of this program is reminded that the geometry of the TDR detector is fairly complicated, and no warranty is given that the implementation in Brahms is correct. Care should be taken when interpreting results.

The intended user of the code will tend to be interested more in the details of detector design, or in physics studies where simple smearing is not appropriate, rather than in general physics studies. For this reason (and due to time constraints) the code has not been fully optimised for the general user.
