Ion Chambers

The ionization chamber or ion chamber is conceptually the simplest of all gas-filled radiation detectors, and is widely used for the detection and measurement of ionizing radiation. It is the preferred device for proton therapy dose and beam position monitoring due to a combination of robustness, gain stability, very low material budget in the beam path and availability of large continuous sensing areas.

Pyramid offers a wide range of ionization chambers for proton and heavy ion therapy applications. Advanced electrode coating and patterning allows the creation of precise strip and pixel patterns for position readout. A wide range of sensitive areas and electrode gaps is provided to suit different system geometries and beam currents.
