How do I define constants?

All attribute values are evaluated by the JDOM expression factory.

<constant name="myval" value="2.0 * cm"/>    

After being defined, constants can be used from anywhere in the compact description. This is useful for reusing values in detector definitions.

What are the compact descriptions default units?

What "magic" constants are expected by the compact reader?

How do I define a magnetic field map (RZB)?

How do I define a new material?

The org.lcsim package can parse a field map with a line-oriented format. This gives the magnetic field strength at a given radius (r) and z.

r z Br Bz

Reference a field map from the compact description.

add detector conditions such as sampling fractions?

These can be added to the LCDetectors directory for a detector tag. See existing detectors such as sid00 for examples.

How do I create my own subdetector type?

• define Java type in org.lcsim.geometry.subdetector
• define LCDD convertor in org.lcsim.geometry.compact.converter.lcdd

What is org.lcsim?

...

org.lcsim?

The org.lcsim package uses the Java programming language, which is generally much easier to get started with and use than C++, especially for those with only partial time to devote to ILC research, as is the case for so many contributors in detector simulations. The org.lcsim package is integrated into JAS3, which is also used by the GLAST and BaBar collaborations and others in HEP research, framework is a Java-based reconstruction and analysis package which has a plugin to JAS3. JAS3 provides a number of integrated tools such as the WIRED event display and an AIDA-compliant plotter.

How do I install org.lcsim?

Developers can use these instructions for building lcsim.

Users who just wish to use the Event Browser and Event Display can simply install the JAS3 plugins.
