Achieving the theoretical maximum light yield in scintillating fibers through non-uniform doping

It is shown that non-uniform doping of scintillating and wavelength shifting fibers can be used to produce the theoretical maximum light yield for any combination of fiber material and fluors. It is calculated that a threefold increase in light yield is possible. Other doping profiles may be used where high speed timing behaviour is the major objective. (orig.). Letter-to-the-editor
