| The design and realization of the fast data readout system of the PET based on photosensitive wire chamber are reported in this article. We have successfully used the technique of multi-grade data buffers, multi-segment pipeline and the DSP processor in the system. Only 540 ns is needed to download the data of one event from front-end modules, and data throughput of the system has reached 200 k-events/s. |
