Removal of Cerenkov Light in Fiber-optic Radiation Sensor Using Optical Filters [PDF]

open access: yesKorean Journal of Optics and Photonics, 2006
In this study, a miniature fiber-optic radiation sensor has been developed using a water-equivalent organic scintillator for electron beam therapy dosimetry. The intensity of Cerenkov light is measured and characterized as a function of the incident angle of the electron beam from a LINAC.
