A research and development study is in progress on high-energy heavy-ion irradiation techniques toward the production of track-etched membranes at the TIARA cyclotron. Up to now, we have succeeded in developing the following basic techniques, the uniform-beam formation and the operation of a roll-to-roll system, which are suitable for irradiation of long-scale polymer films. As a next step, we have considered the efficiency of the operation and irradiation in the roll-to-roll system toward the mass production of track-etched membranes. Therefore, the uniform-beam formation and roll-to-roll irradiation were investigated in low-vacuum environments for reducing the time of vacuum pumping and sample exchange and the cost of a vacuum-pumping system. As a result, we could get a good prospect for ion irradiation of long-scale polymer membranes at the TIARA cyclotron.
