Description
Summary:In this study, the possibility of online measuring of the average electron beam energy using He-Ne, CO2 lasers and optical laminas is presented. In our method, measuring is based on the depth dose distribution model. The substance in which the depth dose distribution takes place for being exposed to radiation is an optical lamina made of glass. For reading the depth dose curves in this substance, the He-Ne laser featuring the wavelength 632.8 nm and the power 5 mW is used. For rereading the depth dose distribution curve, counting as a necessity for remeasuring the average energy, the CO2 laser is radiated. Using the swept radiation of CO2 laser featuring the wavelength 10.6μm and the power 2–3 W brings about cleaning the previously received doses; in the meantime, reviving the substance for receiving the newly absorbed ones. Comparing the experimental findings and simulating the MCNP software implies that this method measuring the average electron beam energy quite fast could be substituted for the already established ones.
