Reference value measurement is the most important aspect in calibration coefficient assessment. For high energy electron beams, the absorbed doses to water have been measured using two types of plane parallel chambers: TN 34045 (PTW) and NACP-2 (IBA Dosimetry) owned by the secondary standard laboratories. Measurements have been carried out at the Elekta Synergy linear accelerator of the IBA Dosimetry laboratory according to the IAEA TRS 398 protocol. The differences between the obtained dose values were determined for measurements of electron beams with nominal energies of 6 MeV, 8 MeV, 10 MeV, 12 MeV, 15 MeV and 18 MeV. The En numbers show good agreement for the absorbed dose to water quantity achieved by both laboratories.
