Georgios Iakovidis, Theodoros Alexopoulos, Georgios Tsipolitis

摘要:

μ子ATLAS Micromegas活动(MAMMA)专注于基于体块Micromegas技术的大面积μ子探测器的开发和测试。鉴于欧洲核子研究中心大型强子对撞机(sLHC)的光度升级,这些探测器是ATLAS μ子系统升级的候选者。它们将在一个设备中结合触发和精确测量能力。提出了一种在读出电极上方使用电阻条的新型保护方案。电阻式Micromegas探测器的响应和火花特性在N.C.S.R.的串列加速器提供的混合(中子和伽马)高辐射场中进行了成功测试。雅典的德莫克里托斯。Monte-Carlo方法研究了5.5MeV中子对Micromegas探测器的影响。此外,还研究了Micromegas探测器对来自实验设施周围材料上不可避免的中子非弹性散射的光子的响应。

英文摘要:

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.
