Limits on light WIMPs with a germanium detector at 177 eVee threshold at the China Jinping Underground Laboratory

Physical review. D. Particles, fields, gravitation, and cosmology/Physical review. D, Particles, fields, gravitation, and cosmology (2014)

S. K. Liu Qian Yue K. Kang Jianping Cheng H. T. Wong

The China Dark Matter Experiment reports results on light WIMP dark matter searches at the China Jinping Underground Laboratory with a germanium detector array with a total mass of 20 g. The physics threshold achieved is 177 eVee ("ee" represents electron equivalent energy) at 50% signal efficiency. With 0.784 kg-days of data, exclusion region on spin-independent coupling with the nucleon is derived, improving over our earlier bounds at WIMP mass less than 4.6 GeV.6 MoreReceived 21 March 2014DOI:https://doi.org/10.1103/PhysRevD.90.032003© 2014 American Physical Society

Application of PDCA Cycle in the Performance Management System

Q. Du Shanshan Cao Lei Ba Cheng Jun-mo

The market competition worldwide being increasingly fierce, numerous organizations come to realize the importance to enhance their own performances. Therefore, most organizations are questing how to optimize their own performance management (PM). This thesis introduces the basic principle, characteristics and operational procedure of PDCA cycle (plan, do, check and action) and discusses its practical significances to promote the PM. And then the application of PDCA cycle in the PM is elaborated through the analysis on each phase of PM system. Finally, some requirements are put forward which should be followed principally during the cycle. That should bring some reference values to the organization's PM. Hopefully, the thesis could be of help to some organizations and managers.

Search of low-mass WIMPs with ap-type point contact germanium detector in the CDEX-1 experiment

Physical review. D/Physical review. D. (2016)

Wen Zhao Qian Yue K. Kang J. Cheng Y. J. Li

The CDEX-1 experiment conducted a search of low-mass (< 10 GeV/c2) Weakly Interacting Massive Particles (WIMPs) dark matter at the China Jinping Underground Laboratory using a p-type point-contact germanium detector with a fiducial mass of 915 g at a physics analysis threshold of 475 eVee. We report the hardware set-up, detector characterization, data acquisition and analysis procedures of this experiment. No excess of unidentified events are observed after subtraction of known background. Using 335.6 kg-days of data, exclusion constraints on the WIMP-nucleon spin-independent and spin-dependent couplings are derived.

Carrier-envelope phase stabilized 5-fs laser and generation of continuum XUV radiation

Hao Teng Chenxia Yun Hainian Han Jiangfeng Zhu Xin Zhong

Coherent extreme-ultraviolet (XUV) radiation was studied by interaction of carrier-envelope (CE) phase stabilized high energy sub-5-fs infrared (800 nm) laser pulses with neon gas at a repetition rate of 1 kHz. The results show generation of isolated attosecond XUV pulses.

Search for Light Weakly-Interacting-Massive-Particle Dark Matter by Annual Modulation Analysis with a Point-Contact Germanium Detector at the China Jinping Underground Laboratory

Physical Review Letters (2019)

L. T. Yang H. B. Li Qian Yue Hao Ma K. J. Kang

We present results on light weakly interacting massive particle (WIMP) searches with annual modulation (AM) analysis on data from a 1-kg mass p-type point-contact germanium detector of the CDEX-1B experiment at the China Jinping Underground Laboratory. Datasets with a total live time of 3.2 yr within a 4.2-yr span are analyzed with analysis threshold of 250 eVee. Limits on WIMP-nucleus (χ-N) spin-independent cross sections as function of WIMP mass (m_{χ}) at 90% confidence level (C.L.) are derived using the dark matter halo model. Within the context of the standard halo model, the 90% C.L. allowed regions implied by the DAMA/LIBRA and CoGeNT AM-based analysis are excluded at >99.99% and 98% C.L., respectively. These results correspond to the best sensitivity at m_{χ}<6 GeV/c^{2} among WIMP AM measurements to date.

Limits on light weakly interacting massive particles from the CDEX-1 experiment with ap-type point-contact germanium detector at the China Jinping Underground Laboratory

Physical review. D. Particles, fields, gravitation, and cosmology/Physical review. D, Particles, fields, gravitation, and cosmology (2014)

Qian Yue Wen Zhao K. Kang J. Cheng Y. J. Li

We report results of a search for light Dark Matter WIMPs with CDEX-1 experiment at the China Jinping Underground Laboratory, based on 53.9 kg-days of data from a p-type point-contact germanium detector enclosed by a NaI(Tl) crystal scintillator as anti-Compton detector. The event rate and spectrum above the analysis threshold of 475 eVee are consistent with the understood background model. Part of the allowed regions for WIMP-nucleus coherent elastic scattering at WIMP mass of 6-20 GeV are probed and excluded. Independent of interaction channels, this result contradicts the interpretation that the anomalous excesses of the CoGeNT experiment are induced by Dark Matter, since identical detector techniques are used in both experiments.

SUB-NANOSECOND TIMING SYSTEM DESIGN AND DEVELOPMENT FOR LHAASO PROJECT*

Guanghua Gong Shaomin Chen Q. Du Jianming Li Yinong Liu

The Large High Altitude Air Shower Observatory (LHAASO) project is designed to trace galactic cosmic ray sources by approximately 10,000 different types of ground air shower detectors. Reconstruction of cosmic ray arrival directions requires a precision of synchronization down to sub-nanosecond, a novel design of the LHAASO timing system by means of packet-based frequency distribution and time synchronization over Ethernet is proposed. The White Rabbit Protocol (WR) is applied as the infrastructure of the timing system, which implements a distributed adaptive phase tracking technology based on Synchronous Ethernet to lock all local clocks, and a real time delay calibration method based on the Precision Time Protocol to keep all local time synchronized within a nanosecond. We also demonstrate the development and test status on prototype WR switches and nodes.
