The Muon ATLAS Micromegas Activity (MAMMA) focuses on the development and testing of large-area muon detectors based on the bulk-Micromegas technology. These detectors are candidates for the upgrade of the ATLAS Muon System in view of the luminosity upgrade of Large Hadron Collider at CERN (sLHC). They will combine trigger and precision measurement capability in a single device. A novel protection scheme using resistive strips above the readout electrode has been developed. The response and sparking properties of resistive Micromegas detectors were successfully tested in a mixed (neutron and gamma) high radiation field supplied by the Tandem accelerator, at the N.C.S.R. Demokritos in Athens. Monte-Carlo studies have been employed to study the effect of 5.5 MeV neutrons impinging on Micromegas detectors. The response of the Micromegas detectors on the photons originating from the inevitable neutron inelastic scattering on the surrounding materials of the experimental facility was also studied.
An ageing study of resistive micromegas for the HL-LHC environment
电阻阳极微兆气体探测器已经开发了几年,以解决在高通量和高电离辐射下工作时的火花问题,如在HL-LHC中(高达LHC亮度的十倍)。它们已被选为ATLAS新小轮项目(前向μ子系统)的技术之一。老化研究是强制性的,以评估它们长期处理HL-LHC环境的能力。一个原型已经暴露于几种类型的辐射(X射线,冷中子,$^{60}$ Co γ和α)以上的等效电荷在五个HL-LHC运行年的探测器在增益和能量分辨率方面的性能没有显示出任何退化。这项研究已经完成了跟踪性能的表征效率和空间分辨率方面,验证了与电阻micromegas探测器,辐照和非辐照的一个获得的结果的兼容性。
