| Research Abstract |
We developed a high performance reference feeble light source composed of a scintillator and a gamma-ray source. This light source is useful to precisely measure the stability of feeble light measurement instruments, because the amount of luminescence from the scintillator depends only on the half-life of the gamma-ray source under the same configuration. A BGO crystal with the large efficiency for gamma rays was used as a scintillator. The feeble light was measured with an integrating sphere 6 inch in diameter, a photomultiplier tube, a photo diode and a spectrometer with a light guide of a plastic fiber. In this system, the amount of luminescence from the BGO scintillator was precisely measured, which led to successful calibration of conventional devices such as luminometers.
