摘　　要：RF cold test of a novel C-band cavity beam position monitor （PBM） to be used in the SDUVFEL Test Facility is described. The test results are presented and some characteristics discussed. The main parameters obtained are in reasonable agreement with the analytical estimations. Effective suppression of the common mode has been demonstrated. The position sensitivity over the test region of μ0.5 mm is about -21.58 dB/10 μm for the TM110 mode and is linear in the central region of the BPM cavity.RF cold test of a novel C-band cavity beam position monitor （PBM） to be used in the SDUVFEL Test Facility is described.
