CALL FOR PROPOSAL OF EXPERIMENTS AT “HIMAC”

Caution: NIRS will be integrated into a new organization in April, 2016. The following conditions may be subject to change.

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 April 2017 through February, 2018.
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 : himac_riyou@qst.go.jp
Surface mail : Department of Accelerator and Medical Physics
National Institute of Radiological Sciences
4-9-1 Anagawa, Inage-ku, Chiba 263-8555, JAPAN

3. Deadline for Submission of Proposals

November 11, 2016

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 researchers inside and outside of NIRS will review all proposals. The final selection of approved experiments will be informed by the Director General of Clinical Research Cluster 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. A summary of the proposal should be presented using the attached form: “Proposal for Research Project with Heavy Ions at NIRS-HIMAC“.
  2. Information describing details of the proposal should be presented on separate sheets in either Japanese or English using guidelines in the attached form: “Instructions for Preparation of Details of the Proposal“
  3. Application to become a collaborative researcher at NIRS using the attached form: “Application Form for a Collaborative Researcher“

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 - <2.5 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 <1.0 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 290 MONO, SOBP60
C 135, 350, 400 MONO
Ne 230 MONO
Ne 400 MONO, SOBP60
Si 490 MONO
Ar 500 MONO
Fe 500 MONO

A diameter of the beam is 100 mm.

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