"Farmer" Type Ion Chamber FC65-P

The Farmer type chamber FC65-P is an air cavity ionization chamber, vented through a waterproof silicon sleeve. It is waterproof and fully guarded.

The watertight chamber consists of a conducting plastic thimble outer electrode and a pure aluminum inner electrode, which are supported by a thin aluminum stem. The stem is connected to a 1.40-m cable shielded by a watertight silicon sleeve that allows for air ventilation.

The chamber is designed preferably for the energy ranges of photons and electrons at medical accelerators. It can also be employed in X-ray beams with generating potentials from 70 kV to 280 kV and for gamma radiation of 137Cs and 60Co. The energy range of proton beams with available chamber factors is between 50 and 250 MeV.

Parallel Plate Ion Chambers for Electron Beam PPC05

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.

Parallel Plate Ion Chambers for Electron Beam PPC40

PPC40 Parallel plate ion chamber for electron beams, 0.4 ccm
As designed and constructed by PTB Braunschweig, M. Roos, K. Derikum, D. Lange. The chamber is entirely made from PMMA; electrode areas are additionally graphitized. The waterproof chamber is vented through a silicone sleeve and it is constructed with a circular sensitive volume of planar geometry covered by a rigid 1 mm thick front window.

The combination of design and material minimizes perturbation components, the in-scattering and the backscatter effect, to a perturbation correction factor equal to unity.
As an associated measuring instrument for precise absolute dose determinations, in calibration dosimetry, compliance testing or installation and set-up of treatment machines or other new equipment, it is recommended to use the reference-class therapy dosimeter Dose1 or Dose2.

NACP Parallel Plate Ionization Chamber

The NACP Chamber is designed according to the recommendations of the Nordic Association of Clinical Physicists (NACP).

The collecting electrode is manufactured of graphitized polystyrene. The Parallel Plate NACP Chamber is produced by IBA Dosimetry, Germany.

The major part of NACP chamber cable is surrounded by a transparent and water-proof plastic tube to protect from water and ensure the active volume ventilation when the chamber is immersed in water.

Inside the tube, there are two humidity indicators. The indicator colour changes according to the humidity of the environment. Only white colour of the indicator indicates that the humidity is suitable for the chamber operation.

The Stealth CHAMBER The StealthCHAMBER is designed to ensure that a reference signal is available for all field sizes (up to 20x20cm with special focus in SRS, SBRT, small field dosimetry commissioning and QA) in continuous and/or in step-by-step scanning mode.
Available with TNC Triax connector.
 
It can be securely mounted with custom or vendor-specific holders in the beam where it does not shadow the field chamber/detector for the entire area of programmed positions, in order to produce accurate and reproducible scans.

RFD Diode Reference Detector The reference detector is used only to obtain a reference signal for relative field measurements. By calculating the quotient of the field and the reference signals, the effect of the variations in the accelerator output is eliminated. rfd diode reference detector.jpg
Razor Detector

Diode detector with very low dose rate dependency, effective measurement depth 0.50 mm from surface, very high geometric resolution (0.6 mm in plane perpendicular to central axis, 0.06 mm in depth).

The Razor detector for relative dosimetry is a very small sized, rigid and long-lasting semiconductor detector with high dosimetric performances.

The Razor detector is based on a p-type silicon diode chip, specifically designed for radiation therapy applications, and in particular for the relative dosimetry of electron and stereotactic photon fields. Performances have been verified in the range of photon beam qualities 60Co-15MV, and 6-15MeV electron energies.
