A Large Area PPAC for Using in Tumor Therapy with Heavy Ions

    Graphical Abstract
    • Abstract
  • he principle of the heavyion therapy is introduced in this article. In order to precisely determine the irradiation profiles and positions of scanned heavyion 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 αsource. As compared with the similar devices, we consider the position resolution of the PPAC can satisfy the requirement of the facility of heavyion therapy.
