우리는 MgB 기반 중성자 회절계 시스템을 제안합니다.2 박막 검출기 및 SFQ 신호 프로세서. MgB의 작은 크기2 SFQ(Single Flux Quantum) 회로의 박막 검출기와 높은 처리 능력을 통해 극저온 냉각기에서 수천 개 이상의 검출기를 처리할 수 있어 매우 컴팩트한 시스템을 구현할 수 있습니다. 또한 시스템은 다양한 운동 에너지에 대한 다양한 회절 패턴을 동시에 제공할 수 있습니다. SFQ 시간-디지털 변환기(TDC)를 사용하여 비행 시간법을 통해 개별 중성자에 대한 운동 에너지를 결정합니다. TDC의 디지털 출력은 시간 영역에서 다중화되어 적은 수의 케이블을 사용하여 실온 전자 장치로 전송됩니다. TDC와 멀티플렉서를 포함한 이중 입력 SFQ 신호 프로세서는 20ns의 시간 분해능과 400μW의 전력 소비로 성공적으로 시연되었습니다. 이러한 값은 여기서 제안된 중성자 회절 시스템의 높은 타당성을 보여줍니다.

Abstract: We propose a neutron diffractometer system based on MgB2 thin film detectors and an SFQ signal processor. Small dimensions of MgB2 thin film detectors and high processing capability of the single flux quantum (SFQ) circuits enable us to handle several thousand or more detectors in a cryocooler, leading to a very compact system. In addition, the system can provide many diffraction patterns for different kinetic energies simultaneously. Kinetic energy is determined for individual neutrons by means of the time-of-flight method by using SFQ time-to-digital converters (TDCs). Digital outputs of the TDCs are multiplexed in time domain and sent to room-temperature electronics with reduced number of cables. A dual-input SFQ signal processor including TDCs and a multiplexer has been successfully demonstrated with a time resolution of 20 ns and power consumption of 400 µW. These values show high feasibility of the neutron diffraction system proposed here.
