Abstract: he principle of the heavyion therapy is introduced in this article. In order to precisely determine the irradiation profiles and positions of scanned heavyion beams, we developed a large area parallel plate avalanche counter(PPAC). The detector consists of one anode, two cathodes and two windows with 250 mm×250 mm active area . It was measured at an anode voltage of 700 V and with flowing C3F8 gas at the pressure of 700 Pa. A position resolution of 0.54 mm by correction was obtained with an αsource. As compared with the similar devices, we consider the position resolution of the PPAC can satisfy the requirement of the facility of heavyion therapy.
