The photons are designed to be tagged with energies of 62%~96% with respect to the circulating electron energy of the BST ring. The duty facto is approximately 50% (stable photon beam can be obtained for 8.5 s out of a 17 s cycle). The number of tagging channels are 116. The details of the photon beam properties are under investigation. Information before The Great East Japan Earthquake (March 11, 2011) can be obtained in a reference “The second GeV tagged photon beamline at ELPH”
