Abstract:
Terbium-activated radioluminescent fiber-optic face plates have been studied for their suitability as electron scintillators. The energy conversion efficiency of such material is determined to be about 2.5% in the electron energy range of 100-400 keV tested. The resolution is approximately 40 microns at electron energy of 100 keV, as measured by the rise width of an edge. The main advantage of such a device is the potential simplification of CCD camera designs, since it functions both as a scintillator as well as a light guide so that it can be coupled direct to a CCD detector.
