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.

In order to cure the transverse coupled bunch instabilities due to higher order modes of RF cavities and resistive wall impedance in the BEPCII storage ring, an analog bunch-by-bunch feedback system was designed and used. The main components are two sets of beam oscillation detectors, betatron phase adjuster, notch filter and stripline kicker. This paper will describe system parameters, specifications of key components and experiment results.
