High-Intensity Deuteron Linear Accelerator (FMIT)

Present Status of High-intensity Proton Accelerator Facility in Japan

The construction of the Project for High-intensity Proton Accelerator Facility(Figure 1). in Japan has been started this year. The Japan Hadron Facility of KEK1 and the Neutron Science Project of JAERI2 merged to this project. The purpose of this Joint Project is to pursue frontier science in particle physics, nuclear physics, materials science, life science and nuclear technology. Accelerators...

Craniospinal Irradiation in Medulloblastoma using High Energy Medical Linear Accelerator: an Innovative Approach to Planning Technique

Background: Craniospinal irradiation (CSI) of medulloblastoma poses technological challenges due to the involvement of large treatment volume. Commonly, the whole treatment length is covered with two different isocentric plans in which the junction is shifted after every five fractions to overcome the possibility of hot and cold spot.Objective: This study aims to evaluate dosimetrically and cli...

Status of a High Current Linear Accelerator at Csns

China Spallation Neutron Source (CSNS) consists of an H linac as an injector of a rapid cycling synchrotron of 1.6 GeV. The 324 MHz rf linac is designed with beam energy of 81 MeV and a peak current of 30 mA. The linac design and R&D are in progress. A test stand of a Penning ion source is under construction. RFQ technology has been developed in ADS study, with beam energy of 3.5 MeV, a peak cu...

Deuteron at High Proton Momenta

The differential cross section and target asymmetry components of the reaction D(e, pp)eπ on polarized deuteron were measured. The kinetic energies of the protons were measured within 55-180 MeV and 46-265 MeV and the acceptance angles in lab. frame are Θ1,2 = 64 − 82, ∆φ1,2 = 32 . The sharp peak of the tensor a20-component of the target asymmetry is found near the invariant mass of the ppπsyst...
