全硅ATLAS ITk探测器，高亮度LHC项目的顶点和跟踪设备，应在最终峰值瞬时光度高达7。5 × 10 34 cm − 2 s − 1，相当于每次穿越约200个非弹性质子-质子相互作用。ITk条检测器将由四个桶层和桶每侧前部区域的六个圆盘组成。它们将由称为板条和花瓣的单独结构组成，其生产将需要近18，000个8种不同设计的单面条模块，混合电路携带粘合到传感器表面的前端微电子ASIC。传感元件是高电阻率n-in-p硅条，能够承受高达1。2 × 10 15 n eq /cm 2。经过辐照和未经辐照的试条模块原型都要经过测试程序，包括测试光束活动，并辅以激光和β源测试，以检查它们是否符合探测器的设计要求。
The all-silicon ATLAS ITk Detector, vertexing and tracking device for the High-Luminosity LHC project, should operate at an ultimate peak instantaneous luminosity up to 7 . 5 × 10 34 cm − 2 s − 1 corresponding to approximately 200 inelastic proton-proton interactions per beam crossing. The ITk Strip Detector will consist of four barrel layers and six disks in a forward region on each side of the barrel. They will be composed of individual structures called staves and petals, whose production will require almost 18,000 single-sided strip modules of 8 different designs with the hybrid circuits carrying the front-end microelectronics ASICs glued to the sensor surface. The sensing elements are high resistivity n-in-p silicon strips capable of withstanding fluences up to 1 . 2 × 10 15 n eq /cm 2 . Both irradiated and non-irradiated prototypes of strip modules undergo testing procedures including test beam campaigns supplemented by laser and beta source tests to check if they meet the design requirements of the detector.
