Study of the solar anisotropy of cosmic ray primaries of about 200 GeV energy with the L3+C muon detector

Eduardo Sanchez, Horst Vogel, Aurelio Bay, Yu Lei, Jian Zhao, Liang Sun, Qian Wang, Zhirui Xu, Matthias Weber, Ji Hyun Kim, Werner Lustermann, Xiao Wang, Yifei Guo, Xuan Yang, Zheng Wang

Context. Primary cosmic rays experience multiple deflections in the non-uniform galactic and heliospheric magnetic fields which may generate anisotropies. Aims. A study of anisotropies in the energy range between 100 and 500 GeV is performed. This energy r ...

A GSM-GPRS/UMTS FDD-TDD/WLAN 802.11a-b-g multi-standard carrier generation system

Michel Declercq, Adil Koukab, Yu Lei

A compact carrier generation system enabling proper interoperability among quad-band GSM, WCDMA (FDD and TDD), and WLAN (802.11a/b/g) standards is developed. The implementation is achieved in 0.25-mum BiCMOS-SiGe process. The measured tuning range is highe ...

A search for flaring very-high-energy cosmic gamma-ray sources with the L3+C muon spectrometer

Eduardo Sanchez, Horst Vogel, Aurelio Bay, Yu Lei, Jian Zhao, Camille Haller, Liang Sun, Qian Wang, Zhirui Xu, Matthias Weber, Ji Hyun Kim, Werner Lustermann, Xiao Wang, Yifei Guo, Xuan Yang, Zheng Wang

The L3+C muon detector at the CERN electron-positron collider, LEP, is used for the detection of very-high-energy cosmic gamma-ray sources through the observation of muons of energies above 20, 30, 50 and 100 GeV. Daily or monthly excesses in the rate of s ...
