Propomos um sistema de difratômetro de nêutrons baseado em MgB2 detectores de filme fino e um processador de sinal SFQ. Pequenas dimensões de MgB2 detectores de filme fino e alta capacidade de processamento dos circuitos quânticos de fluxo único (SFQ) nos permitem lidar com vários milhares ou mais detectores em um resfriador criogênico, resultando em um sistema muito compacto. Além disso, o sistema pode fornecer vários padrões de difração para diferentes energias cinéticas simultaneamente. A energia cinética é determinada para nêutrons individuais por meio do método de tempo de voo usando conversores de tempo para digital (TDCs) SFQ. As saídas digitais dos TDCs são multiplexadas no domínio do tempo e enviadas para eletrônicos em temperatura ambiente com número reduzido de cabos. Um processador de sinal SFQ de entrada dupla incluindo TDCs e um multiplexador foi demonstrado com sucesso com uma resolução de tempo de 20 ns e consumo de energia de 400 µW. Estes valores mostram alta viabilidade do sistema de difração de nêutrons aqui proposto.

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.
