Features
- Suitable for calibration of ionization chambers in high-energy photon and electron beams
- Suitable for monitor calibration in water
- Makes it possible to irradiate up to three chambers simultaneously
- Makes it possible to vary the measuring depth from 15 mm up to 250 mm in increments of 5 mm
The water phantom type 4322 is designed for calibration measurements in radiation therapy using a horizontal beam. Up to three ionization chambers (alternatively TL detectors and FeSO4 ampoules) can simultaneously be placed at different water depths with a distance of 50 mm from chamber axis to chamber axis by using appropriate waterproof acrylic adapters. The external phantom dimensions are approximately 30 cm x 30 cm x 30 cm. The entrance window in one of the walls has the thickness of 3 mm and the size of 150 mm x 150 mm. Holding devices on the top and on the bottom of the phantom make it possible to position the chambers precisely by means of adapters in depths from 15 mm up to 250 mm in increments of 5 mm. The phantom has two handles for easy carrying, three adjustable supports for leveling, etched cross hairs for alignment and a collision protected drain tap for emptying without tilting or changing the phantom’s position.
