RCNP-Z-705 2009. 7. 10 This is the call for new proposals as well as updated proposals for experiments at the Laser-Electron Photon Facility at SPring-8 (LEPS). The LEPS is open to everybody in scientific research. The proposals may be submitted to the Director of RCNP at any time. The RCNP Q-PAC (Program Advisory Committee for the LEPS experiment)* evaluates scientific values and feasibilities of the proposed experiments. The result of the Q-PAC is submitted to the Director. Q-PAC meets at least once a year and reviews research programs received more than two weeks in advance of the Q-PAC meeting. The spokesperson or one of his colleagues is requested to give an oral presentation of the proposal at Q-PAC. According to the recommendation of Q-PAC, the experiment for accepted proposals will be supported by the LEPS/RCNP. Each spokesperson should contact the LEPS division leader, Prof. Takashi Nakano, for scheduling the beam-time. The LEPS Facility and the present status is found on the Web page for reference of proposals. URL is http://www.rcnp.osaka-u.ac.jp/Divisions/np1-b/index.html . The backward-Compton scattering of laser photons from 8 GeV electrons produces linearly or circularly polarized photon beam. The maximum energy and intensity are dependent on the laser sources. The photon energy can be tagged with a typical resolution of 15 MeV in the energy region above 1.5 GeV. The tagging rate is typically 10^6 Hz for the beam with the maximum energy of 2.4 GeV. The new beam with the maximum energy of 2.96 GeV is now available, although the intensity is still not so high, around 2x10^5 Hz. A forward spectrometer for charged particles and a time-projection chamber (TPC) surrounding small target region are available for the experiment at LEPS. Since we have no additional budget except for the standard operation of the LEPS beam to support approved experiments, it is strongly recommended that the spokesperson tries to get such outside funds as a grant-in-aid for the proposed experiment. The next Q-PAC meeting will be held on October 2 (Friday), 2009. ^^^^^^^^^^^^^^^^^^^^^^^^^^^ The deadline of proposals to be reviewed in the coming Q-PAC is September 18 (Friday), 2009. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The format of a proposal is free. However it should include the following information. The official language is English. 1. COVER PAGE : Title of a proposal, Spokesperson (name, affiliation, position, email address), A collaborator list (name, affiliation, position), Beam running time, Requirements for the beam condition and experimental equipment. 2. SUMMARY OF PROPOSAL: 3. DETAILED DESCRIPTION OF PROPOSED RESEARCH: Objectives and Impacts of the experiment, Experimental method and apparatus, Estimation of the beam time requested, Experimental schedule, Equipment provided by the experimental group, if any. There is no charge for use of the beam and existing experimental facilities. In return, all the results obtained from an experiment should be open to public. A copy of any published papers resulting from the work at LEPS must be sent to the RCNP director. For the detailed information about the beam and facilities at LEPS, please contact Prof. T. Nakano (nakano[at]rcnp.osaka-u.ac.jp). * Present Q-PAC committee S. Ajimura RCNP, Osaka University A. Hosaka RCNP, Osaka University D. Jido Kyoto University E. Hiyama RIKEN T.
