In order to develop new beam species of highly charged noble gas ions, we have constructed an in-terminal heavy ion injector in the JAEA-Tokai tandem accelerator using a compact ECR ion source. This work was associated with a lot of development to operate the ion source on the 20UR Pelletron high voltage terminal in high pressure SF$$_{6}$$ gas environment. Highly charged ions of N, O, Ne, Ar, Kr and Xe have been accelerated satisfactorily. Operating data integrated during many years long beam delivery service are summarized.

In FY2006, a tandem accelerator was operated for 201days. The maximum voltage was 18 MV and the accelerated ion species was 19 elements (26 nuclides). As the trouble case which occurred previous year, the change of the beam shape occurred often in the injection beam line of the tandem accelerator. The cause was the contact failure of the pole connector of the electrostatics quadrupole lens. Generally, it was difficult to confirm the connection status of the opened pole but we specified a connection abnormal part by the capacitive coupling method. This technique is useful technology which can be applied to the other electrostatics optics elements. Because the charging electric current flowed only about usual about 60% and the terminal voltage became unstable, we opened a tank and checked the charging system. As a result, a problem was confirmed to the damaging of resistance and the installation of the cable. In the seminar, the operation, maintenance and the accelerator development of the tandem accelerator in FY2006 are described.

The monitoring of EDZ (Excavation Disturbed Zone) is one of the most important required technologies for the design of rock caverns such as the high-level radioactive waste repository. The authors developed the stress-based evaluation system of EDZ by AE monitoring and DEM (Distinct Element Method) simulation. In order to apply this system to the soft rock site, the authors try to grasp the relationship between AE parameters, stress change and rock failure by performing the high stiffness tri-axial compression tests including AE measurements on the soft rock samples, and its simulations by DEM using bonded particle model.
