  • We suggest a method for probing the quark content of the photon using b tagging at high energy e{sup +}e{sup {minus}} and e{gamma} colliders. We find that heavy quark tagging provides a sensitive and effective probe of the quark content of the photon especially in the low x region where the various models differ the most. This process is complementary to others that have been studied in the literature and can contribute to more precise determinations of quark and gluon distributions inside the photon. {copyright} {ital 1997} {ital The American Physical Society}
  • 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{sup +}e{sup -} 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% E{sub {gamma}}. The absolute energy scale was determined using the e{sup +}e{sup -} rate measurements close to the end-point of the photonmore » spectrum. The energy variations across the full tagging range were found to be <3 MeV.« less
