The solid state phantom type 2966 is designed according to ICRU report 231 and consists of a 200 mm x 200 mm x 120 mm acrylic block with a chamber hole and a 200 mm x 200 mm x 30 mm plate. The phantom makes it possible to place thimble chambers in measuring depths of 50 mm, 70 mm and 100 mm. The reference chamber and the chamber under calibration can be placed in the phantom tip-to-tip and irradiated simultaneously, which is the preferred calibration method if both chambers are of the same type. A variety of adapters for a number of ioni-zation chamber types is available. The phantom has a 3/8 inch thread by which it can be mounted on a tripod to avoid backscatter radiation.
