WebThe two ionization chambers used were the PTW Advanced Markus parallel plate chamber and the PTW PinPoint small volume chamber. For each of the dosimeters, percentage depth doses were measured in water over the full range of x-ray beams and for field sizes ranging from 2cm diameter to 12 × 12cm. In addition, depth doses were measured for a ... Webtheir reference point, except for the PTW Advanced Markus (PTW, Freiburg, Germany) chamber whose EPOM coincides with the refer-ence point. Lacroix et al.19 found the EPOM of the NACP‐02 (IBA‐ Scanditronix, Uppsala, Sweden) chamber to be between 0.4 mm for 6 MeV and 1.2 mm for 18 MeV (below the entrance window). Looe

Webthe NACP-02, PTW Roos and Classic Markus ionisation chambers are 1.001 and 0.2 cGy-1 respectively. For the Advanced Markus chambers it can be seen in general the values for c are in good agreement with those of other chamber types. However, m is of the order of 0.04 cGy-1, which is very different to that of the Classic Markus and
