MicroLion Ionization Chamber

Liquid filled ion chamber for dose distribution measurements in radiotherapy with high spatial resolution

MicroLion Ionization Chamber
 

Features

  • Liquid filled sensitive volume of 0.002 cm3
  • Suitable for dose scanning in radiotherapy beams with a superior spatial resolution
  • Suitable for use in water Connector types: BNT, TNC or M

The waterproof micro liquid ion chamber1 (microLion) has been specially designed for relative beam profile and depth dose curve measurements in a motorized water phantom. It is used for characterization of LINAC radiation fields where superior spatial resolution is desired, like stereotactic fields. Due to the liquid filling, the microLion chamber delivers a high signal in relation to its very small sensitive volume.

The recommended chamber voltage of 800 V is delivered by an additional HV-Supply. The HV-Supply can be connected to the UNIDOSwebline or the latest versions of the TANDEM dosemeter.

  1. The microLion chamber was designed in collaboration with G?ran Wickman and Thord Holmstroem, University of Ume?, Sweden and is based on a well-tested and patented LIC concept.
