Bragg Peak 150 Type 34089
The PTW Bragg Peak 150 is a very large area plane-parallel chamber for dosimetry in proton beams. It is designed to measure the exact location of the Bragg peak in the therapy proton beams. The large diameter of the chamber allows the measurement of the proton pencil beam diameter including the beam halo.
The PTW Bragg Peak chamber is waterproof and can be used in air behind a water column or in a water phantom. In water the chamber is very suitable for measurement of horizontal beams. It is also possible to use it in measurements of vertical beams in different water depths due to the thickness of the entrance and exit window. Chamber voltage is 400 V norminal.
0.125 cm3 Semiflex Chamber - Type 31010
The 0.125 cm3 Semiflex Chamber - Type 31010 is a standard therapy chamber for scanning systems and for absolute dosimetry. It is
waterproof with semiflexible design for easy mounting in scanning water phantoms. It is waterproof aswell as minimized in directional response.
The sensitive volume is 0.125 cm3, vented to air, with radioactive check device (option).
The 0.125 cm3 Semiflex Chamber type has a minimized directional response.
