摘要:

大型强子对撞机的beauty(LHCb)探测器是为了探测b-和c-强子的衰变而设计的,用于CP破坏和稀有衰变的研究。在LHC运行2结束时,许多LHCb测量仍然在统计上占主导地位。为了增加纯强子通道的触发产额,将取消硬件触发,并在40 MHz下读出探测器。这与亮度增加五倍相结合,需要对LHCb的电子设备进行彻底的改变,并且在某些情况下,用最先进的探测器技术替换整个子探测器。围绕交互区域的顶点顶点集(VELO)用于重建碰撞点(主顶点)和长寿粒子的衰减顶点(次顶点)。升级后的VELO将由52个模块组成,这些模块沿梁轴放置,分为两个可伸缩的半部分。每个模块将配备4个硅混合像素瓦片,每个瓦片由3个VeloPix ASIC读出。预计整个探测器的总输出数据速率约为1.6 Tbit/s。最高占用率的ASIC将具有大约900 Mhit/s的像素命中率,对应的输出数据速率为15 Gbit/s。LHCb升级探测器将是第一个以40 MHz的LHC全速率读出的探测器。VELO的升级将利用最新的探测器技术,以这一速度读出,同时保持所需的抗辐射剖面,并尽量减少探测器材料。

英文摘要:

The Large Hadron Collider beauty (LHCb) detector is designed to detect decays of b- and c- hadrons for the study of CP violation and rare decays. At the end of the LHC Run 2, many of the LHCb measurements remained statistically dominated. In order to increase the trigger yield for purely hadronic channels, the hardware trigger will be removed, and the detector will be read out at 40 MHz. This, in combination with the five-fold increase in luminosity, requires radical changes to LHCb's electronics, and, in some cases, the replacement of entire sub-detectors with state-of-the-art detector technologies. The Vertex Locator (VELO) surrounding the interaction region is used to reconstruct the collision points (primary vertices) and decay vertices of long-lived particles (secondary vertices). The upgraded VELO will be composed of 52 modules placed along the beam axis divided into two retractable halves. The modules will each be equipped with 4 silicon hybrid pixel tiles, each read out by 3 VeloPix ASICs. The total output data rate anticipated for the whole detector will be around 1.6 Tbit/s. The highest occupancy ASICs will have pixel hit rates of approximately 900 Mhit/s, with the corresponding output data rate of 15 Gbit/s. The LHCb upgrade detector will be the first detector to read out at the full LHC rate of 40 MHz. The VELO upgrade will utilize the latest detector technologies to read out at this rate while maintaining the required radiation-hard profile and minimizing the detector material.
