Persistence of two phosphors that are used in X-ray image intensifiers. (a) P46, (b) P43. In (a), the current in an ion chamber (S-1329A, Oken, Tokyo, Japan) is also shown. The X-ray shutter began to cut the beam at time zero. The final level of the decay corresponds to the offset of the analogue-to-digital converter. |
