Software to perform ray-tracing simulations for the SST-GATE telescope

The following code can be used for ray-tracing studies of the SST-GATE telescope. This code was written in c++ and has been tested using the clang++ compiler: Apple LLVM version 8.1.0 (clang-802.0.42) on an Apple Macbook Pro running macOS Sierra version 10.12.6

In order to use this software properly a working copy of the CERN ROOT analysis framework is required. Currently this software has only been tested on the production version ROOT v6.10.06 (see https://root.cern.ch)

In addition, for this software to work a copy of the ROBAST software version 2.4.4 must be installed.

You must define the the ROBAST environment variable so CMake can find your ROBAST installation.

i.e. export ROBAST=path/to/your/ROBAST/installation

For more information about ROBAST please see http://robast.github.io/

The latest ROBAST releases are available from https://github.com/ROBAST/ROBAST/releases

In addition you need to have CMake installed. This software was tested with CMake version 3.7.2 The minimum version supported is version 2.8

To install the SST-GATE simulation software:

git clone sst-gate-v2-0-0-source

cd sst-gate-v2-0-0-source

git checkout -b v2-0-0 v2-0-0

cd ../

mkdir sst-gate-v2-0-0-build sst-gate-v2-0-0-install

cd sst-gate-v2-0-0-build

cmake -DCMAKE_INSTALL_PREFIX=/full/path/to/sst-gate-v2-0-0-install ../sst-gate-v2-0-0-source/

The cmake build system supports parallel builds. You can specify the option -jN where N is the number of cores you have available.

cmake --build . -- -j2

cmake --build . --target install

export PATH=${PATH}:/path/to/sst-gate-v2-0-0-install/bin

You are now ready to test the SST-GATE software, you can do this from the command line by running:

./sst_gate_test 2.0 test-run square 0.0 0.0

ZEMAX data files are contained within the zemax_data_files directory located within the extras directory. Also included in the zemax_data_files directory is an internal technical note on the optical design written by Jürgen Schmoll (University of Durham).

If you use or fork this software you must credit the original authors in all your works. In particular you should always include the following reference:
