Recent Developments of Micromegas Detectors for High Energy Physics
P. Colas
Since one or two years, Micromegas detectors have broken records in many respects: time and spatial resolution, single electron detection, low ion backflow, high rate capabilities, low energy threshold and low-noise detection. The recent achievements in these directions, obtained in the COMPASS, NA48 (KABES), and CAST experiments, and in R&Ds for the Linear Collider TPC and for low-energy neutrino detection, are presented. The reasons for such a success, inherent to basic properties of Micromegas, are explained.
