CALYPSO

CALYPSO is a small library that allows to included the luminosity spectra calculated with GUINEA-PIG into event generators. After initialisation each call to a routine CALYP returns the energies of two colliding particles. All the correlations are properly taken into account. The only drawback is that a large input file is need for each collider configuration. In order to use CALYPSO, you need to download the library, maybe the documentation, and the input files.

Also a small program exists that can generate the electron-positron, electron-photon, photon-positron and photon-photon collisions at CLIC with Ecm = 3 TeV and nominal parameters. It uses fits to the CALYPSO data. This program does not need any input files. You can download it here. You have to compile and link it to the CERN library. It will later become part of the calypso library.

The Library

The CALYPSO library can be downloaded here. The file needs to be gunzip-ped and then un-tar-red using

gunzip clypso.tar.gz

tar -xf calypso.tar

It can then be compiled by

make all

The Documentation

A very rough introduction can be found here

The Input Files

The luminosity file can be found here for the latest CLIC parameters at 3TeV in 2008.

The old input files that are necessary to use CALYPSO can be found here.

Files for Ecm = 0.5 TeV

Files for Ecm = 1 TeV

Files for Ecm = 3 TeV

Files for Ecm = 5 TeV
