The Micromesh Gaseous Structure (Micromegas) detectors designed and developed by IRFU researchers have been used increasingly over the past few years in the field of particle and radiation detection for physics research, and show strong potential for nuclear, biomedical and industrial instrumentation applications. Recent R&D efforts have led to the development of new manufacturing processes that improve the performance and scope of application of these detectors. The second generation of Micromegas detectors is already being used in several international physics experiments that have yielded excellent results since the fall of 2008.

This large gas detector is based on a simple, strong and low-cost spherical geometry. The detector combines a large drift volume and proportional amplification in order to detect ionising particles. A metal ball at the centre of the sphere is held at a high voltage causing an avalanche effect in the gas surrounding it.
Target applications:
- Low energy neutrino physics
- industrial applications involving the detection of neutrons
On November 14, 2008, the Compact Muon Solenoid (CMS) successfully generated a nominal magnetic field of 4 tesla. This success rewards IRFU efforts for the design and construction of what constitutes the largest superconducting solenoid magnet in the world. Over a period of approximately one month, CMS teams conducted a continuous data acquisition campaign with the detector operating under nominal conditions. Approximately 300 million cosmic events were recorded. This also provided an excellent opportunity to showcase the specific expertise of IRFU teams, particularly in areas such as detection systems, electronics, trace data reconstruction techniques and laser control systems.
