Air Ionization Chambers

Compact Chambers

Applications

All compact chambers are designed for measurements with high reproducibility in air, in solid or in water phantoms. They are suitable for relative dosimetry of photon, electron and proton fields in radiotherapy.

CC01
CC01
CC04
CC04		 CC01 and CC04 are the conventional ionization chambers for measurements of small fields and of ranges with high dose gradients, e.g. stereotactic fields.
CC08 is used for customized applications during manufacturing and installation of linear accelerators (e.g. "Buddelship").
CC13 is the standard chamber for clinical use in water phantoms and for output factor measurements. 		CC08/CC13
CC08/CC13
CC25 is mainly used for quality assurance in air and for low dose measurements in water phantoms. CC25
CC25
The CC13-S is replacement for RK chamber used in RFA phantoms. Parameters of the CC13-S are similar to CC13. CC25
