	In recent years, the production of radionuclides for Targeted Radionuclide Therapy (TRT) with the NIRS-930 cyclotron has been one of the most important activities in National Institutes for Quantum and Radiological Science and Technology (QST), National Institute of Radiological Sciences (NIRS). In the production of 211At, for example, a target material with low melting point is irradiated with a high intensity beam. A vertical beam line have the advantage in irradiation with low-melting-point target. Therefore a vertical beam line has been modified for the production of radionuclides. This line was used for neutron source with beryllium target. The beam intensity and beam energy are important parameters for the effective production of radionuclide for TRT. In order to increase beam intensity, the acceleration phase and injection energy have been optimized by measuring beam phase. The beam energy has been measured by TOF and adjusted by tuning the acceleration frequency. Those studies and improvement are reported.
