Electron and photon fields for dosimetric metrology generated by electron beams from a microtron

Final results of investigation of collimating systems for the generation of electron and photon fields for dosimetric metrology are presented together with basic information concerning the circular microtron used as a source of relativistic electrons for metrological purposes. Isodose plots of the photon and electron fields and absorbed depth dose curves for photon energies of 10 and 19 MeV and electron energies of 9.8, 14.6 and 18.7 MeV demonstrate the possibility of using a circular microtron as a source of homogeneous and symmetrical fields for calibration of dosimetric devices.
