Research Project with Heavy Ions at NIRS-HIMAC >

October, 2002

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 FY 2003. This corresponds to the period from April, 2003 through February, 2004. 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.
    E-mail : muraka_t@nirs.go.jp
    Fax : +81-43-251-1840
    Mail : Division of Accelerator Physics and Engineering
    National Institute of Radiological Sciences
    4-9-1 Anagawa, Inage-ku, Chiba 263-8555, JAPAN
  3. Deadline for Submission of Proposals
    December 13, 2002

  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.
    (2) Details of the proposal. Additional information should be presented on separate sheets in either Japanese or English.
    (3) "Application Form for a Cooperative 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.

    -- Physics --
    Ion Energy(MeV/u) Intensity
    pps(particles / second)
    He 100 180 230 - - - - - 1.2 x 10^10
    C 100 180 230 290 350 400 430 - <1.8 x 10^9
    N 100 180 230 290 350 400 430 - <1.5 x 10^9
    O 100 180 230 290 350 400 430 - <1.1 x 10^9
    Ne 100 180 230 290 350 400 600 - <7.8 x 10^8
    Si 100 180 230 290 350 400 600 800 <4.0 x 10^8
    Ar - - - 290 - 400 650 - <2.4 x 10^8
    Fe - - - - - 400 500 - <2.2 x 10^8

    -- 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--
    Ion He, C, N, O, Ne, Si, Ar, Fe
    Energy 6 MeV/u
    Intensity <2.0 x 10^11 pps

    -- 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).
    Ion energy (MeV/u) field shape
    He 150 MONO, SOBP60
    C 135 MONO
    C 290 MONO, SOBP60, SOBP60(200), SOBP120
    C 350 MONO
    C 400 MONO
    Ne 230 MONO
    Ne 400 MONO, SOBP60
    Si 490 MONO
    Ar 500 MONO
    A diameter of the beam is 100 mm unless otherwise noted.

    SOBP60(200) indicates an SOBP field with a thickness in depth of 60 mm and a diameter of 200 mm. Maximum intensity is approximately 5 Gy/min. for a MONO beam and 3 Gy/min. for an SOBP beam.
