Overview

Start

In collaboration with High Energy Accelerator Research Organization (KEK) and Japan Atomic Energy Agency (JAEA), the linac complex, which was developed in Institute of Nuclear Study, University of Tokyo, was moved to Tandem Accelerator facility in Tokai area of JAEA from April in 2004. From 2005, RNB's of 1.1 MeV/nucleon have been supplied for users.

Future Plan

The present beam line will be connected to the exsisting super conducting linac which was developed for booster of Tandem accelerator. By the connection, RNB of 5-8MeV/nucleon will be provided. TRIAC will be one of the most advanced RNB facility.

Research Activity

a) Nuclear Astrophysics
The nucleo-synthesis in novae, which is so called rapid-process or r-process, is considered to consist of the multi-step neutron-capture reaction and the &beta decay of neutron-rich nuclei. We are going to measure the cross sections of the reaction and the propeties of the decays. As well as r-process, we are going to study the reactions related to the rapid-hydrogen burning process, rp-process, and the primordial synthesis in the early universe.

b) Nuclear Physics
We are going to study mechanism of the nuclear reaction involving neutron-rich nuclei and produce a super-heavy element, by using the RNB produced by the nuclear-fission of Uranium target.

c) Nuclear Chemistry
Electrons at the most external orbits in very heavy atoms move with the relativistic velocity. The relativistic effect makes the mass of electron heavier so that the energy level schemes of atoms or molecules will be changed drastically compared to the elements in the same group. We are going to study such relativistic effect through some fast chemical reactions.

d) Material Science
The radioactivity emitted from RNB can be used as non-destructive probe. By injection of RNB into the materials and measurement of their radioactivity, we are going to study the internal structures of the materials and the dynamics of RNB in the materials. These studies will contribute to the the development of new batteries and so on.
