Overview

This guide will explain how to generate physics events in an HPS setup including the ECal and the tracking detectors. Reconstruction and analysis is performed on the ECal data only.

Preliminaries

The Maven 2 tool must be installed locally (not covered here), as well as a Java JDK.

...

mkdir hps
cd hps

Build SimDist

In order to get a working version of slic, follow the
SimDist Build Instructions.

...

/nfs/slac/g/lcd/mc/prj/sw/dist/SimDist/pro/scripts/slic.sh

hps-detectors

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

...

This will locally install the HPS detector data.

Run Event Simulation

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

...

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