X-Ray Therapy Monitor Chamber 7862

Large size plane-parallel transmission chamber for use as dose monitor combined with X-ray therapy units

The circular plane-parallel transmission chamber model 7862 is used for dose monitoring in combination with radiotherapy X-ray units. The sensitive volume is designed as a very thin cylinder of 2.4 mm thickness and 96.5 mm diameter. The chamber wall and the electrode are made of polyimide (Pl) of 0.05 mm thickness each with graphite layer, mechanically protected by another Pl foil of 00.05 mm in front of each wall. The nominal photon energy range is 7.5 kV up to 420 kV and the leakage current is less than 1 pA. The chamber housing is 119.5 mm. Three holes with 3.5 mm threads serve for mechanical chamber fixation. The transmission chamber model 7862 is used in connection with dosemeters having th input circuits on ground potential.

Key Features

  • Vented sensitive volume of 17.6 cm³
  • Shadow-free transmission chamber for dose monitoring with radiation therapy X-ray equipment
