Mobile Single Ion Track Irradiation System


  • Material: polymer tape, 36 mm wide, 5 to 100 µm thick
  • Frame width: typically 25 mm
  • Irradiation angles: 35.1 or 90 degrees with respect to surface
  • Spot size: typically 0.5 mm diameter
  • Ion flux: typically 1 ion per s


  • Worldwide unique mobile irradiation system
  • Irradiated 10 000 polycarbonate single track membranes of 30 µm thickness
  • Irradiated counted track membranes with up to hundred ions per irradiation spot
  • Irradiated polyimide, polycarbonate, and polyesther membranes between 10 and 50 µm thickness
