Workshop Purpose

       The purpose of the workshop is to study the background issues in the BEPCII/BESIII. Some experimental data and preliminary analysis of the BEPCII background measurement will be presented in the workshop. Experiences and results on background study in such factory-type e⁺-e^- colliders/detectors as PEP-II/BaBar, KEKB/Belle and DAFNE will be presented in the workshop. On the base of these data, the workshop will intensively discuss and study the background issues in the BEPCII/BESIII in order to determine if the radiation level is low enough for the BESIII detector to roll into the interaction region of the BEPCII and to foresee the background and noise in the detector during its data taking. Simulation and experimental study on the backgrounds could be arranged during the workshop.
