| Abstract(in English) | We have demonstrated an SFQ signal processor prototype composed of quasi-one-junction SQUID (QOS) comparators, time-to-digital converters (TDCs), and a multiplexer for a MgB_2-nanowire neutron detector array system. The system will be compact and produce diffraction patterns for different values of neutron energy simultaneously. We have examined the operation of the signal processor prototype by providing the QOS comparators with external currents instead of detector output currents. The QOS comparators generate an SFQ pulse for each clock with a frequency of 12.8GHz if the currents exceed a certain threshold. The time resolution of the TDCs studied here is 20ns. The time-division multiplexing for the two outputs of the TDCs has also been confirmed with the time difference of 10ns. |
