| Popis: | Extending, the lifetime of amorphous silicon based radiation imagers is necessary for numerous applications including industrial inspection and radiation therapy. To achieve a longer lifetime, a new pixel design has been fabricated. This design incorporates a gated diode that significantly increase mitigates the effect of radiation damage. Additionally, each pixel incorporates a storage capacitor to increase the dynamic range of the pixel and a reflective layer to maximize the light collection efficiency. We report on the device performance of this design and the imaging performance of the complete detector. |
