We have measured the gas bremsstrahlung photon energy from the 2.5-GeV electron storage ring at the Pohang Light Source (PLS). Gas bremsstrahlung was generated in the straight section of the beam-diagnosis beamline 1C1 with an effective length of 5.3 m. We present the measurement results for the bremsstrahlung photon energy spectrum and the photon flux, which were obtained by using a CeF 3 calorimeter, The calorimeter consisted of nine CeF 3 blocks, each being 3.3 × 3.3 × 33 cm 3, stacked into a 3 × 3 array. The bremsstrahlung photon flux above 40 MeV was measured to be 218 s -1 at an electron beam current of 180 mA.
