چکیده انگلیسی
In this report, we present the energy calibration of the Hall B bremsstrahlung tagging system at the Thomas Jefferson National Accelerator Facility. The calibration was performed using a magnetic pair spectrometer. The tagged photon energy spectrum was measured in coincidence with e+e-e+e- pairs as a function of the pair spectrometer magnetic field. Taking advantage of the internal linearity of the pair spectrometer, the energy of the tagging system was calibrated at the level of ±0.1%Eγ±0.1%Eγ. The absolute energy scale was determined using the e+e-e+e- rate measurements close to the end-point of the photon spectrum. The energy variations across the full tagging range were found to be <3MeV.
