Microscintillator radioactivity detector

项目摘要

Traditionally, Geiger counters are used as radiation detectors; however, they are limited by their inability to determine the energy of the radiation they measure. This project involves development of a new miniature radioactivity detector, a "microscintillator" which is similar to a Geiger counter, but with the added benefit that it can measure the energy of the radioactive particle. The device is able to measure count rates, analogous to a Geiger counter, but can also differentiate between the different energies of incoming particles. It is also small and low-power enough for use in airborne applications; we believe it is the smallest and cheapest detector of its type available. It has already been trialled on high-altitude balloons and uncrewed airborne vehicles (UAVs), and units are being sold to researchers around the world.The goal of this project is to carry out technical development of the instrument, such as discrimination of different particle types through simple pulse shape identification, and optimization of the detector and measurement system. The student will also use both physics and engineering software to model the device's response and better understand and characterize its measurements in the atmosphere or in space.The project involves a collaboration with Dr Alec Bennett at Biral, a leading developer and manufacturer of meteorological technology, to investigate commercialization of the instrument for the environmental science market. Most of the project will be based at Bristol University, but some time (by arrangement) will also be spent working at Biral's research and manufacturing facility at Portishead near Bristol.

传统上，盖革计数器被用作辐射探测器;然而，它们受到无法确定它们测量的辐射能量的限制。该项目涉及开发一种新型微型放射性探测器，即一种“微闪烁体”，类似于盖革计数器，但其额外好处是可以测量放射性粒子的能量。该装置能够测量计数率，类似于盖革计数器，但也可以区分入射粒子的不同能量。它体积小，功耗低，足以用于机载应用;我们相信它是同类产品中最小和最便宜的探测器。该仪器已经在高空气球和无人机上进行了试验，并正在向世界各地的研究人员出售。该项目的目标是进行仪器的技术开发，例如通过简单的脉冲形状识别来区分不同的粒子类型，以及优化探测器和测量系统。学生还将使用物理和工程软件来模拟设备的响应，并更好地理解和表征其在大气或太空中的测量结果。该项目涉及与Biral的Alec班尼特博士合作，Biral是气象技术的领先开发商和制造商，旨在研究该仪器在环境科学市场的商业化。该项目的大部分工作将在布里斯托大学进行，但也有一部分时间（根据安排）将在比拉尔位于布里斯托附近波蒂黑德的研究和制造工厂工作。
