Abstract
The dosimetric response of a multi guard ring structure (MGR) diode has been studied with clinical electron beam energies from 5â¯MeV to 15â¯MeV. The results showed that the MGR dose response is linear in the range of 5-320â¯cGy and presents reproducibility with variation coefficients less than 0.4%. The field output factors measured with the MGR agreed within 2% with those measured with an ionization chamber. This study evidences that this diode can be used for clinical electron beam dosimetry.
