우리는 초전도 터널 접합(STJ)을 기반으로 고해상도 X선 검출기용 판독 장치로 초전도 아날로그-디지털 변환기(ADC)를 개발하고 있습니다. ADC에는 DC SQUID(초전도 양자 간섭 장치)로 구성된 민감한 프런트 엔드가 있습니다. 신호 전류는 프리앰프를 사용하지 않고 이 프런트 엔드에 의해 디지털화됩니다. 주파수가 입력 전류에 비례하는 단일 플럭스 양자(SFQ) 펄스 트레인은 프런트 엔드에서 시작되고 디지털 카운터에 의해 통합됩니다. 카운터의 분해능은 10비트이며 통합된 값은 스캔되어 40MHz 주파수의 실온 처리 모듈로 전송됩니다. 본 논문에서는 ADC의 설계를 기술하고, ADC 성능 테스트의 예비 결과를 제시한다. ADC를 수반하는 STJ의 성능은 X선 에너지 분해능 측면에서 논의됩니다.

Abstract: We are developing a superconducting analog-to-digital converter (ADC) as a readout for high-resolution X-ray detectors based on a superconducting tunnel junction (STJ). The ADC has a sensitive front end which consists of a DC superconducting quantum interference device (SQUID). A signal current is digitized by this front end without using any preamplifiers. A single-flux-quantum (SFQ) pulse train whose frequency is proportional to the input current is launched by the front end, and integrated by a digital counter. The counter has a 10-bit resolution, and the integrated value is scanned and transferred to room-temperature processing modules with a frequency of 40 MHz. In this paper, the design of the ADC is described, and the preliminary results of the ADC performance test are shown. The performance of the STJ accompanied by the ADC is discussed in terms of the X-ray energy resolution.
