1 What is SHADOW

SHADOW is an open source ray tracing code for modeling optical systems.

Targeted to synchrotron radiation beamlines, it has unique features for designing X-ray optical systems.

For more info, please read this paper (open access):

• M. Sanchez del Rio, N. Canestrari, F. Jiang and F. Cerrina "SHADOW3: a new version of the synchrotron X-ray optics modelling package" Journal of Synchrotron Radiation Volume 18, Part 5 (September 2011) http://dx.doi.org/10.1107/S0909049511026306

If you are (or want to be) a SHADOW user, it is recommended that you use a user interface. We strongly recommend OASYS (https://www.aps.anl.gov/Science/Scientific-Software/OASYS) with its ShadowOui add-on. Information can ba found at these papers:

Note also that the ShadowOUI interface implements the hybrid ray-tracing method explained at:

2 Installing SHADOW

In most cases, shadow3 is used within the OASYS package, therefore there is no need to install it independently (install OASYS from https://www.aps.anl.gov/Science/Scientific-Software/OASYS ).

To install shadow3 in python, you can use pip or conda:

• https://pypi.org/project/shadow3/
• https://anaconda.org/conda-forge/shadow3

3 Building SHADOW

SHADOW3 sources are downloaded using git:

git clone https://github.com/oasys-kit/shadow3

To build the command-mode shadow3 version:

cd shadow3/src
# Check (edit) the Makefile if you need to redefine compilers etc.
# The use of Makefile is documented in its header. Basically:
make           : builds shadow3 the main program
make all       : builds shadow3, libraries, etc

to build the python API:

in shadow3 directory, use the standard python setup (see comments in setup.py for specific platforms):

python setup.py sdist build
python setup.py bdist_wheel
python -m pip install dist/...whl
