	RIKEN RI Beam Factory is one of the world-leading heavy-ion facilities where nuclear physics research and application research have been conducted. One important application, performed more than twenty years at RIBF, is breeding plants and others where energetic heavy ions are used as very effective mutagens. Our previous main accelerator RIKEN Ring Cyclotron has been used for this purpose but available beam energies and resultant ion ranges are limited for medium heavy ions such as argon and iron ions. Hence, a new beam transport line delivering beams accelerated by one of our new-generation cyclotrons, RIKEN Intermediate Ring Cyclotron, to E5H experimental vault, where biological samples are irradiated in air, has been constructed. We will report design of the new beam line and the results obtained by the beam-commissioning test performed using a 160 MeV/nucleon argon beam in January 2015. We obtained performances as designed, for example, nearly 100% transmission efficiency, and a threefold increase of ion ranges. The higher-energy argon beam delivered by the new beam line was used to induce seaweed mutations immediately after the beam test.

RIKEN RI Beam Factory is one of the world-leading heavy-ion facilities where nuclear physics research and application research have been conducted. One important application, performed more than twenty years at RIBF, is breeding plants and others where energetic heavy ions are used as very effective mutagens. Our previous main accelerator RIKEN Ring Cyclotron has been used for this purpose but available beam energies and resultant ion ranges are limited for medium heavy ions such as argon and iron ions. Hence, a new beam transport line delivering beams accelerated by one of our new-generation cyclotrons, RIKEN Intermediate Ring Cyclotron, to E5H experimental vault, where biological samples are irradiated in air, has been constructed. We will report design of the new beam line and the results obtained by the beam-commissioning test performed using a 160 MeV/nucleon argon beam in January 2015. We obtained performances as designed, for example, nearly 100% transmission efficiency, and a threefold increase of ion ranges. The higher-energy argon beam delivered by the new beam line was used to induce seaweed mutations immediately after the beam test.
