Notes to foreign researchers on CALL FOR PROPOSALS.
1. Due to rising energy costs, HIMAC's operating procedures will be changed.
Basically 2 days/week of machine time can be allocated in the second half of FY2024.

Only the biological irradiation room and the medium-energy beam irradiation room are available.

hours.

The bio-irradiation room is available on a frame-by-frame basis, with each frame is two to three
The assignment grade by the PAC will be reflected in the machine time assignment. Even if yourproposal is accepted, machine-time may not be assigned based on the results, preferences, or otherconditions.

CALL FOR PROPOSAL OF EXPERIMENTS AT "HIMAC"
1. Description

National Institutes for Quantum and Science and Technology (QST) - Quantum Life and Medical Science Directorate in Chiba,
Japan, will accept proposals for experiments using Heavy Ion Medical Accelerator in Chiba (HIMAC) during the period from
September 2024 through March 2025. Although HIMAC is an accelerator designed for medical applications, beam time isavailable for research projects beyond the scope of medical sciences.
* "Notes to foreign researchers on CALL FOR PROPOSALS." is attached. Please be sure to read it before applying.
* This call for proposals is an additional call for 2024. If your proposal has already been accepted, you do not need to apply.

2. Address for Submission of Proposals

Additional information and instructions for submission of proposals are available from the Program Coordinator at thefollowing address.

4-9-1 Anagawa, Inage-ku, Chiba 263-8555, JAPAN3. Deadline for Submission of Proposals
June 17, 2024

4. Description of Facilities

Two experimental halls are available for research at HIMAC. These include facilities for Biology, and Medium-Energy Beams.
HIMAC is used for medical application. Other research can only be basically performed on Tuesday night.

5. Eligibility

Any persons with research experience as well as graduate students are eligible to be participants in the experiments, no otherrestriction is imposed. However, it is required that “one or more scientists from QST-Chiba join the research group” to provide
administrative and technical advice. Please contact the Program Coordinator for assistance in identifying this local person atQST (liaison at QST) before the submission.

6. Spokesperson

One of participants in the proposal should be identified as the spokesperson. All correspondence with QST should be throughthis spokesperson.

7. Review and Selection of the Proposals

A Program Advisory Committee (PAC) consisting of researchers inside and outside of QST will review all proposals. The final
selection of approved experiments will be informed by the Managing Director of Quantum Medical Science Directorate basedon 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 QST for each experiment will work with abeam-time coordinator at QST 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 atQST -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 QST using the attached form: “Application Form for a CollaborativeResearcher”, “Oath concerning Research Misconducts”, and “Pledge for Security Export Control”.
* Caution! Exporting samples, material, devices, and transferring all kinds of data and information are regulated by “SecurityExport Control”.

10. Available BeamsCharacteristics of typical beams are listed below. Additional ions or energies may be available in a limited manner uponrequest. Please contact the Program Coordinator for more information.

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

* Due to a change in the operation method of HIMAC caused by rising energy costs,physics beamlines other than the medium-energy beamlines are not available.
