The Large Underground Xenon experiment (LUX) searches for dark matter using a dual-phase xenon detector. LUX uses a custom-developed trigger system for event selection. In this paper, the trigger efficiency, which is defined as the probability that an event of interest is selected for offline analysis, is studied using raw data obtained from both electron recoil (ER) and nuclear recoil (NR) calibrations. The measured efficiency exceeds 98\% at a pulse area of 90 detected photons, which is well below the WIMP analysis threshold on the S2 pulse area. The efficiency also exceeds 98\% at recoil energies of \mbox{0.2 keV} and above for ER, and \mbox{1.3 keV} and above for NR. The measured trigger efficiency varies between 99\% and 100\% over the fiducial volume of the detector.
GPU Enhancement of the Trigger to Extend Physics Reach at the LHC
高能物理实验不断面临重大的新挑战，特别是欧洲核子研究中心大型强子对撞机的两个探测器，在标称条件下，质子-质子碰撞以40 MHz的速率传递到探测器。必须显著降低该速率，以符合大容量存储硬件的性能限制和计算资源的能力，从而以及时的方式处理所收集的数据以进行物理分析。同时，必须高效地保留感兴趣的物理信号。在大型强子对撞机上对罕见的新物理现象的探索使我们评估了现有高级触发器（HLT）的图形处理单元（GPU）增强，这是由触发系统的当前灵活性实现的，它不仅提供了更快，更有效的事件选择，而且还包括以前不可行的新复杂触发的可能性。在NVIDIA Tesla K20 c GPU上评估了一种新的跟踪算法，首次允许在触发器中的跟踪器系统中重建长寿命粒子。将介绍初步的时间性能和效率。

Experience gained about Resistive Plate Chambers ageing from the ALICE Muon TRigger/IDentifier detector
ALICE μ子鉴别器由72个单间隙酚醛树脂电阻板室组成，自2009年以来一直在使用四氟乙烷/异丁烷/六氟化硫混合气体的最大雪崩模式（鉴别阈值：7 mV，无放大）下运行，计数率为数十Hz/cm ^2。在这次演讲中，RPC系统的长期性能和稳定性将在效率，暗电流和暗速率方面进行讨论。将对探测器上观察到的潜在老化迹象进行评估，并总结最常见的硬件问题。
