Bragg Peak^® 150 Type 34089

Very large area plane-parallel chamber for dosimetry in proton beams

The 34089 Bragg peak chamber is designed to measure the exact location of the Bragg peak in therapy proton beams. The very large diameter of the chamber allows the measurement of the proton pencil beam diameter, including the beam halo. The chamber is waterproof and consequently can either be used in air behind a water column or in a water phantom. In water, the Bragg Peak chamber can be used for measurements of horizontal beams. Due to the thickness of the entrance and exit windows, the chamber can additionally be used in vertical beams where measurements are performed in different water depths.
