Polycrystal generation and meshing.
Neper is a software package for polycrystal generation and meshing. It can deal with 2D and 3D polycrystals with very large numbers of grains. Its main features are: - Generation of polycrystals from (experimental) morphological properties; - Generation of multiscale microstructures; - Generation of periodic or semi-periodic microstructures; - Meshing into good-quality elements; - Meshing with cohesive elements at interfaces; - Visualization and analysis of the tessellations and meshes. Neper is built around three modules: generation, meshing and visualization. All the input data are prescribed non-interactively, using command lines and / or ASCII files. Neper can be compiled and run on any Unix-like system.
A program for fitting structural models to small angle scattering data
SASfit has been written for analyzing and plotting small angle scattering data. It can calculate integral structural parameters like radius of gyration, scattering invariant, Porod constant. Furthermore it can fit size distributions together with several form factors including different structure factors. Additionally an algorithm has been implemented, which allows to simultaneously fit several scattering curves with a common set of (global) parameters. This last option is especially important in contrast variation experiments or measurements with polarised neutrons. The global fit helps to determine fit parameters unambiguously which by analysing a single curve would be otherwise strongly correlated.

PyRPL turns your Red Pitaya into a powerful analog feedback device.
The Red Pitaya is a commercial, affordable FPGA board with fast analog inputs and outputs. This makes it useful for quantum optics experiments, in particular as a digital feedback controller for analog systems. Based on the open source software provided by the board manufacturer, PyRPL (Python RedPitaya Lockbox) implements many devices that are needed for optics experiments with the Red Pitaya. PyRPL implements various digital signal processing (DSP) modules (see features below). It allows to arbitrarily interconnect the available DSP modules and retrieve signal values on timescales below 1 ms. The graphical user interface (GUI) provides a realtime display of the various measurement instruments and allows the easy configuration of DSP signal chains and feedback controllers. At the highest abstraction level, arbitrary feedback sequences can be defined to fulfill tasks as complex as approaching and locking a resonance of a high-finesse Fabry-Perot cavity (tested up to finesse=100,000).

A set of tools for simulating semiconductor nanostructures.
This software accompanies the textbook "Quantum Wells, Wires and Dots" (4th Edition), Paul Harrison and Alex Valavanis, Wiley, Chichester (2015). It is adapted (by the same authors) from code that was originally supplied on a CD with the first edition of the book  and is now made available under the GPL3 license. In brief, we encourage everyone to use the software in your studies and research, to study and modify the source-code and to share it widely. However, you are not permitted to include any of our code in a closed-source project.

The aim of FAZIA project is to build a 4Pi array for charged particles
The FAZIA project groups together more than 10 institutions in Nuclear Physics, which are working in the domain of heavy-ion induced reactions around and below the Fermi energy (10-100AMeV). The aim of the project is to build a 4Pi array for charged particles, with high granularity and good energy resolution, with A and Z identification capability over the widest possible range. It will use the up-to-date techniques concerning detection, signal processing and data flow, with full digital electronics. Neutron detection is also foreseen via the collaboration with the NEUTROMANIA group. FAZIA is designed to operate at stable and radioactive beams facilities like LNL-Legnaro, LNS-Catania in Italy, GANIL-SPIRAL and SPIRAL2 in France, GSI-FAIR in Germany in the horizon 2010-2015. The availability of the european radioactive beam facility EURISOL expected in the period 2015-2020 will also be a major opportunity for the FAZIA community.
