CALL FOR PROPOSAL OF EXPERIMENTS AT "HIMAC"
1. Description
National Institute of Radiological Sciences (NIRS) in Chiba,
Japan, will accept proposals for experiments using Heavy Ion Medical Accelerator
in Chiba (HIMAC) during the period from September, 2005 through February, 2006.
Although HIMAC is an accelerator designed for medical applications, beam time
is available for research projects beyond the scope of medical sciences.
2. Address for Submission of Proposals
Additional information and instructions for submission of proposals are
available from the Program Coordinator at the following address.

4-9-1 Anagawa, Inage-ku, Chiba 263-8555, JAPAN |
3. Deadline for Submission of Proposals
June 30, 2005
4. Description of Facilities
Four experimental halls are available for research at HIMAC.
These include facilities for Biology, Physics, Secondary-Beams, and Medium-Energy
Beams.
HIMAC is used for medical application between 7:00 and 21:00
from Tuesday through Friday. Other research can be performed at night during
the week and all day Saturday. Daytime on Monday is reserved for maintenance
and accelerator development.
5. Eligibility
Any persons with research experience as well as graduate students
are eligible to be participants in the experiments, no other restriction is
imposed. However, it is required that "one or more scientists from NIRS
join the research group" to provide administrative and technical advice.
Please contact the Program Coordinator for assistance in identifying this local
person at NIRS (liaison at NIRS) before the submission.
6. Spokesperson
One of participants in the proposal should be identified as
the spokesperson. All correspondence with NIRS should be through this spokesperson.
7. Review and Selection of the Proposals
A Program Advisory Committee (PAC) consisting of users inside
and outside of NIRS will review all proposals. The final selection of approved
experiments will be informed by the Director of Research Center for Charged
Particle Therapy based on recommendations from the PAC. The approval is valid
for one year. Renewals for continuation or revised proposals must be submitted
each year.
Beam time is scheduled every six months. The spokesperson
and the liaison at NIRS for each experiment will work with a beam-time coordinator
at NIRS to arrange preferred beam times.
8. Travel Budget
Approval of a proposal at HIMAC does not include or imply
support for travel.
9. Submission
Necessary documents for submission include,
(1) "Proposal for Research Project with Heavy Ions at
NIRS-HIMAC". A summary of the proposal should be presented according to
the form, which is included.
(2) Details of the proposal. Additional information should
be presented on separate sheets in either Japanese or English. It should be
6 pages or less.
(3) "Application Form for a Collaborative Researcher".
The form is included.
10. Available Beams
Characteristics of typical beams are listed below. Additional
ions or energies may be available in a limited manner upon request. Please
contact the Program Coordinator for more information.

-- Secondary-Beams --
The same ions and energies as shown for Physics are available
as primary beams. However the intensity is limited to one percent of that listed
for Physics. The production rate of the secondary beams is variable.
-- Medium-Energy Beams --

-- Biology --
A large and uniform irradiation field is provided for Biology. The user
can select a mono-energetic beam with a narrow Bragg Peak (MONO) or a beam
with a broad "Spread-Out" Bragg Peak (SOBP).
