PPC05 is an air-cavity ionization chamber with high spatial resolution.
The construction materials are air equivalent conducting plastic Shonka C552 (housing, entry window and side walls) and highly insulating plastics PEEK and PPE. The collecting electrode material is graphitized PEEK.

The chamber is constructed with a circular sensitive volume of planar geometry covered by a rigid 1 mm thick entry window. The small collecting volume with 0.6 mm plate spacing, 9.9 mm diameter and a 3.4-mm-wide guard ring enables excellent resolution in depth dose studies and requires a small perturbation correction. The chamber is waterproof and vented through a silicone sleeve.
