Waterproof plane-parallel chamber for reference dosimetry in high-energy electron and proton beams

The 34001 Roos chamber is the golden standard for reference dose measurements in high-energy electron beams. Modern dosimetry protocols refer to the chamber’s design and provide dosimetric correction factors. Its waterproof design allows the chamber to be used in water or in solid state phantoms. The Roos chamber is also well suited for the measurement of high-energy photon depth dose curves. The chamber can be used for dose measurements of proton beams.
