Collaborating with Physics Experiments in Laser Electron Photon Facility in SPring-8 ―Toward Construction of The Second Beamline―

Abstract

A close collaboration between accelerator and experimental physicists have been necessary to proceed physics in the laser electron photon facility in SPring-8 (LEPS). After describing how specific features of the LEPS beamline worked and they were necessary for discovering a pentaquark particle, Θ⁺, we show an example of the collaboration in identifying the energy resolution of the γ beam.The demand for a new beamline and its key concepts are shortly mentioned.
