Abstract

In this paper, we aim to present the detector developments for the HISPEC/DESPEC (HIgh-resolution in-flight SPECtroscopy/DEcay SPECtroscopy) collaboration at the Slovenian Nuclear Instrumentation Laboratory. The

Δ E - E

telescope array will be one of the crucial tracking detectors of the HISPEC-10 campaign. A prototype of the

Δ E - E

telescope was constructed along with its cooling. For fast timing measurements, a time resolution of the implantation detectors better than 1 ns and the capability to detect and distinguish between ion implantation and subsequent decays are needed. Scintillating fibres are used for a Fibre IMPlanter (FIMP) to fulfil these requirements. DEGAS (DEspec Germanium Array Spectrometer) is a key instrument of DESPEC and is planned to be operated in most future experimental campaigns. To further improve the sensitivity of the array, shielding of the environmental background with active and passive components is planned. Shielding directly behind the HPGe detectors is based on the BGO scintillation detectors. The BGO detector was characterized, and its performance was compared with a simple gamma-ray propagation simulation.

斯洛文尼亚核仪器实验室HISPEC/DESPEC合作的探测器开发

在本文中，我们旨在介绍斯洛文尼亚核仪器实验室HISPEC/DESPEC（高分辨率飞行光谱/衰减光谱）合作的探测器发展情况。ΔE−E望远镜阵列将是HISPEC-10运动的关键跟踪探测器之一。ΔE - E望远镜的原型连同它的冷却装置一起被建造。为了实现快速定时测量，需要注入探测器的时间分辨率优于1ns，并具有检测和区分离子注入和随后衰变的能力。闪烁光纤用于光纤植入器（FIMP）以满足这些要求。DEGAS （DEspec锗阵列光谱仪）是DEspec的关键仪器，计划在未来的大多数实验活动中使用。为了进一步提高阵列的灵敏度，设计了有源和无源元件对环境背景的屏蔽。hge探测器背后的屏蔽是基于BGO闪烁探测器。对BGO探测器进行了表征，并将其性能与简单的伽玛射线传播模拟进行了比较。
