The facility of the JAERI-Tokai tandem accelerator and its booster has been contributing to advancing heavy-ion sciences in the fields of nuclear physics, nuclear chemistry, atomic and solid-state physics and materials science, taking advantage of its prominent performance of heavy-ion acceleration. This facility was recently upgraded by changing the acceleration tubes and installing an ECR ion-source at the terminal. The radioactive nuclear beam facility (TRIAC) was also installed by the JAERI-KEK joint project. On this occasion, this meeting was held in order to provide a new step for the advancement of heavy-ion science, and to exchange information on recent activities and future plans using the tandem facility as well as on promising new experimental techniques. This meeting was held at Tokai site of JAERI on January 6th and 7th in 2005, having 24 oral presentations, and was successfully carried out with as many as 90 participants and lively discussions among scientists from all the fields of heavy-ion science.

Workshop of Advanced Science Research Center, JAERI Nuclear Physics and Nuclear Chemistry of Superheavy Elements; February 27-28, 2003, Tokai-mura

Workshop on 'Nuclear Physics and Nuclear Chemistry of Superheavy Elements' was held in Advanced Science Research Center of JAERI at February 27-28 (2003). Efforts were paid to produce SHEs in several countries including Germany, Russia, France, and United States. In Japan, the production of element with Z=111 has been reported by RIKEN. In JAERI, investigations on fusion mechanism have been made in order to find an efficient way to produce SHEs. Chemistry on SHEs is quite active. In the SHE region, a wave function of outermost electron, which controls chemical properties of an element, is disturbed or changed by relativistic effects. This suggests that the SHEs have different chemical properties from those of lighter elements belonging to the same family. In the JAERI-tandem facility, chemistry of Rf and Db have been investigated by using actinide targets such as Cm. In the workshop, discussions on the current status and future plans for the heavy element research were made.

The facility of the JAERI tandem accelerator and its booster has been contributing to advancing heavy ion science researches in the fields of nuclear physics, nuclear chemistry, atomic and solid state physics and materials science, taking advantage of its prominent performances in providing various heavy ions. This meeting, as well as the previous ones held twice, offered scientists from the fields of heavy ion science, including nuclear physics, solid-state physics and cross-field physics, an opportunity to have active discussions among them, as well as to review their research accomplishments in the last two years. Oral presentations were selected from a wider scope of prospective fields, expecting a new step of advancing in heavy ion science. Main topics of the meeting were the status of the JAERI-KEK joint project of developing a radioactive nuclear beam(RNB) facility and research programs related to the RNB.

JAERI and KEK-Institute of Particle and Nuclear Studies are collabarating to build an ISOL-type radioactive ion beam(RIB) acceleration system in the JAERI-Tokai tandem accelerator lab. In this project, the tandem accelerator is used as a proton beam driver to create RIB from fission products of a uranium target and a RIB accelerator already built by KEK will be installed in an old target room of the tandem accelerator lab. The beam energy is 1.1 MeV/nucleon, which is not sufficient for experiments related to nuclear reactions. They have a plan to boost the beams to 5 - 9 MeV/u by developing a pre-booster and using existing super-conducting tandem-booster. The plan of this project, acceleration divices and present status will be outlined in the RIB session of the CAARI.
