Description: We use this ionization chamber for relative dosimetry in the water phantom (profiles, depth dose curves, output factors). E.g., TrueBeam output factors (Eclipse beam data) for field sizes > 4x4 cm were measured with this detector.

It is a good general purpose detector for field scanning, if field size is not too small.
