需要满足日益具有挑战性的检测要求（例如大体积物体、非常快的检测吞吐量、潜在的显著屏蔽等）对于核材料和爆炸物等物品，将需要使用主动审讯技术。虽然这些主动技术可以通过诱导独特的时间特征成功地解决这些挑战，但检查环境也将诱导总体“背景信号”，其可以比诱导的特征大几个数量级。探测器，可以成功地在这些类型的定制，检查环境（脉冲和连续），并成功地提取感应签名数据，显然是需要的，并将有效地定义任何主动检查系统的局限性。一种新型的碳化硅探测器，现在正在研究成功地解决中子和光子/韧致辐射类型的检查应用。虽然本文介绍了这种探测器，并突出了与中子检查的努力，它将集中在其中子和伽玛射线/光子探测性能的中子和韧致辐射型检查应用。
The need to address increasingly challenging inspection requirements (such as large volume objects, very fast inspection throughputs, potentially significant shielding, etc.) for such items as nuclear materials and explosives will require the use of active interrogation technologies. While these active technologies can successfully address these challenges by inducing unique, temporal signatures, the inspection environment will also induce overall “background signals” that can be orders of magnitude larger than the induced signatures. Detectors that can successfully operate in these types of customized, inspection environments (pulsed and continuous) and successfully extract induced signature data are clearly needed and will effectively define the limitations of any active inspection system. A novel silicon carbide detector is now being investigated to successfully address both neutron- and photon/bremsstrahlung-type inspection applications. While this paper describes this detector and highlights efforts related to neutron inspection, it will focus on its neutron and gamma-ray/photon detection performance in neutron- and bremssstrahlung-type inspection applications.
