Generating Monte Carlo Data

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
• StdHep events (see Finding Monte Carlo data at SLAC)

Build SLIC

You need a copy of SLIC.

See the SLIC installation instructions.

Detector Data

In your work area, checkout the detector data files from SVN.

svn co svn://svn.freehep.org/hps/java/trunk/detector-data

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 ./detector-data/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
