Waterproof thimble chamber for measuring high-energy photon and electron radiation in water

  • Vented sensitive volume of 0.6 cm3
  • Suitable as therapy chamber for use in water
  • Flat energy response

The 0.6 cm3 PTW Farmer chamber type 30013 is a waterproof standard chamber for absolute photon and electron dosimetry with therapy dosemeters to be used in water or in solid-state material. The nominal photon energy range is from 30 kV to 50 MV, the electron energy range is from 10 MeV to 45 MeV. This chamber type is of rugged construction, since the wall material is graphite with a protective acrylic cover and the electrode is made of aluminum. The guard ring is designed up to the measuring volume. The chamber is supplied with a cable of 1m length. Different connector types are available. A calibration certificate for calibration in absorbed dose to water or air kerma is included with each chamber. Air density correction is required for each measurement. A radioactive check device is available as an option.
