摘要

有机半导体（OSC）技术由于其可调谐、可扩展和具有成本效益的特性而受到积极的科学关注。我们将介绍基于OSC技术的辐射传感器，特别是与探测由α辐射、热中子和快中子组成的强子辐射有关的应用。中子探测在各个领域都很有用，从基本粒子和原子物理研究到医学领域和核安全门户监测。这些有机传感器专注于ndi型有机聚合物，包括一种新型材料，碳硼烷，碳、硼和氢的多面体簇，直接结合在分子骨架中（oCbT2-NDI），通过硼中子捕获（BNC）过程对热中子敏感。与具有均匀分散碳化硼（B4C）微粒的类似聚合物（PNDI(2OD)2T）和不含硼的对高能快中子敏感的控制传感器进行了比较。

Organic semiconductor detectors for alpha and neutron detection

Organic semiconductor (OSC) technologies are of active scientific interest due to their tunable, scalable, and cost-effective nature. We will present radiation sensors based on OSC technology, particularly applications related to detection of hadronic radiation consisting of

α

radiation and thermal and fast neutrons. Neutron detection is useful in various fields, from fundamental particle and atomic physics research to the medical field and nuclear security portal monitors. These organic sensors focus on NDI-type organic polymers including a novel material with carborane, a polyhedral cluster of carbon, boron, and hydrogen, directly incorporated in the molecular backbone (oCbT₂-NDI), sensitising to thermal neutrons via the boron neutron capture (BNC) process. A comparison is made with a similar polymer (PNDI(2OD)2T) with homogeneously dispersed boron carbide (B₄C) microparticles, and a control sensor without any boron which is sensitive to more energetic fast neutrons.

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
