Overview

This guide will explain how to generate physics events in an HPS setup including the ECal and the tracking detectors.

Preliminaries

You will need:

  • SLIC
  • Detector geometry files in hps-detectors (you don't need to build the package)

Build SLIC

You need a copy of SLIC. See the build instructions at: Installing HPS Software

hps-detectors

You must first set CVSROOT to SLAC CVS (example in bash shell; look up how to use "setenv" in csh/tcsh).

export CVSROOT=:pserver:anonymous@cvs.freehep.org:/cvs/lcd

In your work area, checkout the hps-detectors module from cvs.

cvs co hps-detectors

This will locally install the HPS detector data.

Run Event Simulation

The following example shows how to generate some LCIO events using slic.

slic -g ./hps-detectors/detectors/HPS-EcalTest-v1pt0/HPS-EcalTest-v1pt0.lcdd \
-i /nfs/slac/g/hps/mgraham/DarkPhoton/SignalEvents/ap6.6gev100mevsel_10_20u_beamspot_gammactau_0cm.stdhep \
-x -o hpsEcalTest -r 10000

If you do not have SLAC NFS access, sample signal events can be obtained from this ftp space.
