Ion Chambers

Pyramid's transmission ionization chambers are designed to provide high-precision measurements of ionizing radiation in proton and heavy ion therapy applications. With advanced electrode coating and patterning, precise strip and pixel patterns enable accurate position readout. The chambers are available in a range of sensitive areas and electrode gaps, making them adaptable to different system geometries and beam currents.

Ideal for proton therapy dose and beam position monitoring, our ionization chambers are the preferred choice due to their robustness, gain stability, low material budget in the beam path, and large continuous sensing areas.
