Sumario: | The ATLAS New Small Wheels will be the first major upgrade to an LHC experiment utilizing the Micromegas technology. With an active detection area of 1280\,m$^2$ and comprising more than 2 Million channels it is the largest and probably most ambitious system of Micro Pattern Gaseous Detectors (MPGDs) currently under construction. The eponymous component of the Micromegas technology, the micromesh, is the detectors most precise component. Although a wide range of meshes, mesh geometries and -parameters can be used to build an operational Micromegas, it's properties can effect a range of detectors qualities, such as reconstruction efficiency, timing- and energy resolution. Conversely, the correct choice of this component will permit a wider range in operation parameters and optimize the detector performance. |
