A high-resolution on-line isotope separator (ISOL) followed by a long beam transport line is under testing at INS, as a pilot radioactive beam facility for the E-arena of the Japanese Hadron Project. The ISOL has a unique feature in its high-voltage potential configuration; it has two separation stages and both are electrically insulated from the ground. This feature is effective to eliminate impurities as well as to perform high-resolution mass separation while keeping the injection beam velocity to the post accelerator constant. The design concept and present status of performance tests are reported.
