Micro-Pattern Gas Detector (MPGD) have been developed in CEA-Saclay since 1996. MPGDs are gaseous particle detectors coming from the development of wire chambers invented by Georges Charpark (Nobel prize in Physics in 1992). MPGDs can detect particles (photons, neutrons, charged particles) by amplifying the charges that have been created by ionisation in the gas volume.
The group was founded by Ioannis Giomataris, when he invented the Micromegas technology.
In the last decades, technicians, engineers and physicists from Irfu have been contributing actively to the development of MPGD for a wide range of experiments in the fields of particle, nuclear and astroparticle physics.
