PinPoint Ionization Chamber
PinPoint Ionization Chamber
The waterproof 0.015 cm³ PinPoint ionization chamber has been specially designed for stereotactic field measurements in radiation therapy. With its inner diameter of only 2 mm, the PinPoint chamber is ideally suited for relative beam profile measurements in a motorized water phantom where superior spatial resolution is desired.

After calibration by the user in comparison with a calibrated therapy chamber, the PinPoint chamber can be used for depth dose and absolute dose measurements. The sensitive volume is vented. The wall material is graphite with a protective acrylic cover. The guard ring borders the measuring volume. The nominal useful energy range is Co-60 up to 50 MV photons. The chamber has a short stem for mounting and a flexible connection cable. It can be supplied with different connector types.

  • Waterproof chamber with superior spatial resolution for dose measurements in stereotactic high-energy beams
  • Vented sensitive volume of 0.015 cm³
  • Suitable for use in water
