RCNP-Z-725
2011. 1. 15
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 is held 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 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 11 MeV in the energy
region above 1.5 GeV. The tagging rate is 2x10^6 Hz for the beam with
the maximum energy of 2.4 GeV. The new beam with the maximum energy of
2.9 GeV with deep UV lasers is also available, although the intensity
is still not so high, around 2x10^5 Hz. A forward spectrometer for
charged particles and a small time-projection chamber (TPC) surrounding
the target region are available for the experiment at LEPS. Neutron TOF
counters have recently installed just downstream of the usual TOF wall.
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 March 10 (Thursday), 2011.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The deadline of proposals to be reviewed in the coming Q-PAC is
February 28 (Monday), 2011.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
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).
