PyMca has been developed by the Software Group of the European Synchrotron Radiation Facility (ESRF). If you are in doubt about how to pronounce it, just think about how you would spell ?MCA. For the end user, PyMca is a ready to use, and in many aspects state-of-the-art, set of applications implementing most of the needs of X-ray fluorescence data analysis.

For the developer, the PyMca Toolkit is a collection of Python tools for visualization and analysis of energy-dispersive X-ray fluorescence data. It builds its graphic interface and plotting routines on top of the C++ libraries Qt and Qwt through their respective Python bindings PyQt and PyQwt. Nevertheless, the data analysis routines can be used independently of any graphical interface.

In addition to data files, PyMca can also access SPEC shared memory to monitor data acquisitions.
