An isotope separation on-line (ISOL) system is necessary to provide 11C ions for heavy-ion cancer therapy with simul-taneous verification of the dose distribution using positron emission tomography. To realize the ISOL system, we have developed elementary instruments in the ISOL system, such as a proton-irradiation target, a molecule separation system, and a singly-charged ion source, and performed tests to verify their performances. As a next step of the development, we are planning to start an experiment of on-line production of singly-charged 11C ions at the proton irradiation port of the NIRS-cyclotron facility. In this paper, we present those elementary instruments, their performance and the on-line production experiment.
