研究了大型强子对撞机高亮度升级时ATLAS内跟踪探测器的布局对辐射损伤和占有率的影响。利用模拟的粒子通量，我们根据测量的辐射损伤数据评估了信噪比，并估计了预期占有率。跟踪性能模拟得出了不同的入住率，我们发现两者之间存在令人满意的一致性。使用占用和信噪比对位置的依赖关系来评估升级后的ATLAS内部探测器的布局。
We have investigated the layout for the inner tracking detector for ATLAS at the high luminosity upgrade of the LHC with respect to radiation damage and occupancy. Using simulated particle fluxes, we evaluate the signal-to-noise ratio based on measured radiation damage data, and estimate the expected occupancy. Tracking performance simulations yield alternative occupancy numbers and we find satisfactory agreement between the both. The dependence of occupancy and signal-to-noise on the location are used to evaluate the layout of the upgraded ATLAS inner detector.
