Abstract:
| The effect of a diode laser on the optical properties of a thin CN plastic detector was investigated. A laser with a wavelength of (632 nm) and different operating currents were used to control the power of the laser beam falling on the CN detector. The relationship between the laser’s operating current and the intensity measured by the photodetector in the absence of a detector, with a detector that has not been exposed to radiation, and with a number of detectors that have been exposed to radiation with various energies and alpha particles from the americium source (2.3, 3.0, 3.5, 4) MeV in order to research how the photodetector’s detector absorption affects the laser intensity detection. Intensity through the detector is reduced as irradiation with alpha particles is increased, increasing the detector’s absorption and quenching coefficient. |
