Study of Rates in the Radphi Experiment

Abstract A general survey of the rates observed in Radphi detector elements during the 2000 run is presented. Of special interest are the rates extracted for the BGD (barrel gamma detector) and the LGD for which no scaler information was collected. TDC information was used to provide rate information for the BGD. In the case of the LGD the rate information is extracted by a comparison of inclusive spectra collected during minimum-bias runs at high and low beam current. The results show an excellent agreement with Monte Carlo predictions for the rates from electromagnetic background alone. Evidence is seen for rate-dependent effects in the blocks nearest the beam hole.
