Experimental beam-related background study is intro-duced with the BEijing Spectrometor (BESIII) off the interaction region (IR) of the BEPCII [2]. Only safety issues are studied carefully so far for the not good enough detectors’ accuracy. Various experiments are carried out and effective ways to reduce the doses to the IR are found. The results show that the BESIII is safe enough when it is pulled to the IR.

The BEPC (Beijing Electron Positron Collider) is being upgraded as a double-ring factory-like collider (BEPCII). A New and compact interaction region (IR) has been designed to afford a peak luminosity of 10e33 cm-2s-1 with an equal beam energy of 1.89 GeV, a cross angle of +/-11 mrad, 93 bunches and maximum beam current of 0.91 A. All the components of the IR have been fabricated successfully. During the commissioning of BEPCII the operation experience shows that the IR components have excellent performance and meet the design requirements. The design and realization of the interaction region for the BEPCII will be introduced in detail.
