Abstract

Bremsstrahlung gamma radiation and photoneutrons are produced during the operation of high energy linear accelerators. The functionality of electronic devices that are placed inside accelerator tunnels can be jeopardized because of the negative influence of generated radiation. Therefore, a radiation monitoring system able to gauge neutron fluence and gamma dose in real time was constructed. Radiation-sensitive dosimeters cooperate with a readout system. The readout continuously measures both types of radiation and sends quantified data to a main computer. The system is also placed in the tunnel, hence it must be insensitive to radiation or able to tolerate induced malfunctions. A few different readout systems were designed. This work presents the application of different readouts designed using commercial of the shelf (COTS) components. The presented hardware was tested with americium-beryllium neutron source. Finally, the systems were irradiated in a linear accelerator tunnel to estimate their immunity and suitability for a long-term reliable operation in the radioactive field

钐基中子探测器耐辐射读出系统

高能直线加速器在运行过程中会产生轫致辐射和光子中子。由于产生的辐射的负面影响，放置在加速器隧道内的电子设备的功能可能会受到损害。为此，构建了一个能够实时测量中子通量和γ剂量的辐射监测系统。辐射敏感剂量计与读出系统配合使用。读出器连续测量两种类型的辐射，并将量化数据发送到主计算机。该系统也被放置在隧道中，因此它必须对辐射不敏感或能够容忍诱发故障。设计了几种不同的读出系统。这项工作提出了使用商用货架(COTS)组件设计的不同读数的应用。用镅-铍中子源对该硬件进行了测试。最后，在直线加速器隧道中辐照了这些系统，以评估它们的抗扰度和在放射性场中长期可靠运行的适用性
