	Funding: This work has been supported by through KOMAC (Korea Multi-purpose Accelerator Complex) operation fund of KAERI by MSIT (Ministry of Science and ICT) A prototype target ion source was developed in order to produce a radioactive beam such as Li-8 as a part of the goals to establish a platform for secondary particle production at KOMAC (Korea Multi-purpose Accelerator Complex). A beam transport system from the 100-MeV linac to prototype target ion source was designed and constructed. It consists of 8 quadrupole magnets, 2 bending magnets and beam diagnostic devices such as AC current transformers, beam position monitors, beam profile monitors and beam loss monitors.

	Funding: This work has been supported through KOMAC operation fund of KAERI and the NRF of Korea grant funded by the Korea government (MSIT) (No. NRF-2017M2A2A6A02071070). Geant4 physical processes for simulating diffusion and effusion of radioactive ions in matter have been developed for optimizing ISOL target-ion-source (TIS) system. The developed processes simulate motions of radioactive ions with sub-eV kinetic energy in the TIS geometry. The processes consist of diffusion, effusion, and radioactive decay modules, and they are designed to work seamlessly with other implemented physics lists, extending capability of the Geant4 toolkit to more complicated applications in the field of nuclear physics. The diffusion probability is analytically calculated by using the well-known Fick's formula. The effusive flow of neutral atoms is interpreted in terms of kinetic molecular theory of gases, where the interaction between atoms and the wall of a target container is described by employing Lorentz-Lambert model. By the help of newly implemented processes, it is able to simulate the release of radioactive ions from the irradiation of a proton beam on the TIS system with different geometrical parameters in a single environment. Here, we present the status of the development and plans for further improvements.
