Abstract
This letter describes a 16 × 8-pixel array based on single-photon avalanche diodes (SPADs) optimized for the readout of a tracking detector based on plastic scintillation fibers targeting ultra-fast neutrons. Each pixel of 125 × 250 μm2 size contains 30 SPADs,an 80-ps 10-b time-to-digital converter (TDC),a 5-b intensity counter,a finite state machine (FSM) that manages the recording of data and a three-word-deep FIFO memory for parallel acquisition and readout,achieving 32.1% pixel fill factor. A combined,programmable current-based local,and global triggering mechanism correlates the photon detection activity in time to distinguish asynchronous charged particle trace events from background noise even with a poor SNR.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
