Open Source VHDL/Verilog Physics Software

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).

Custom uav is a complete flight control system in development. The project includes everything required for unmanned flight.

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.

Gwyscope is a low cost, open hardware, Digital Signal Processor (DSP) suitable for Scanning Probe Microscopy measurements, focusing on demonstrating the concept of adaptive scanning, general XYZ data acquisition and statistical data processing on the controller level. More details can be found in: M. Valtr et al., Scanning Probe Microscopy controller with advanced sampling support, HardwareX, Volume 15, e00451 https://www.hardware-x.com/article/S2468-0672(23)00058-5/fulltext It is based on a low cost FPGA board Red Pitaya and additional high bit depth AD and DA converters. When put together with the AFM scanning hardware (sensor, scanner and their amplifiers) and user interface software it can serve as a standalone SPM system. Otherwise, it can serve as a sub-module for a custom built SPM system, e.g. providing the feedback loop mechanism only. Finally, it can be used as a board for developing advanced sampling techniques, which was the primary goal.
