| 英文摘要 | Fluorescence lifetime measurement in the time domain requires excitation from a well separated single bunch using synchrotron light sources. in the colliding mode of the beijing electron positron collider ii (bepc ii), a hybrid filling pattern was realized such that a single bunch was placed in the middle of a large gap between two multi-bunch groups. detection of fluorescence lifetime, based on the excitation of the light pulse from this designated single-bunch, was established at beamline 4b8 of the beijing synchrotron radiation facility (bsrf). the timing signal of the bepcii was utilized as a trigger to gate this fluorescence event. l-tryptophan amino acid, a known lifetime standard, was selected to assess the lifetime measurement performance. the measured lifetime was consistent in both colliding and single-bunch mode with the time resolution down to 450 ps. moreover, both the bunch purity and the fine structure of the hybrid filling pattern were characterized. |
