Call for Proposals for Experiments
at the Laser-Electron Photon Facility at SPring-8 (LEPS)
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 ten days 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 the intensity is still
not so high, around 10^5 Hz. A forward spectrometer for charged
particles, a large solid-angle electro-magnetic (EM) calorimeter for
gamma-rays, and a time-projection chamber (TPC) surrounding small
target region are available for the experiment at LEPS. (The EM
calorimeter is now used in the experiment at the Laboratory of Nuclear Science,
Tohoku University, and can not be used at LEPS for a while.)
Another TPC for the liquid hydrogen and deuterium target is now under
construction.
We shall try hard to get budget for approved experiments. It is,
therefore, strongly recommended that the spokesperson tries to get
such outside funds as a grant-in-aid for his proposed experiment.
The next Q-PAC meeting will be held on October 6 (Thursday), 2005.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The deadline of proposals to be reviewed in the coming Q-PAC is
September 26 (Monday), 2005.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
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@rcnp.osaka-u.ac.jp).
