Current combustors rely on the spread of a flame front or shock across the mixture of fuel and oxidizer (deflagration or detonation). This process requires a small but finite period of time, during which conditions often deviate from optimum. Replacing this approach by the simultaneous release of radicals in the whole volume at an optimal time is a desirable but challenging goal. This project examines the practicality of using electron beams to trigger ignition across a large volume. It will be tested also in the break-up of chlorine compounds, since they are chemically very similar to hydrocarbon fuels. The success of the method would ensure the availability of a very useful technological base for the design of efficient non- polluting engines and incinerators. Long term concerns about energy conservation and environment control make the development of this method highly important.

目前的燃烧器依靠火焰前缘或激波在燃料和氧化剂混合物上的传播（爆燃或爆轰）。这一过程需要很短但有限的时间，在此期间，条件往往偏离最佳。在一个最佳的时间，用在整个体积中同时释放自由基来取代这种方法是一个理想但具有挑战性的目标。这个项目考察了使用电子束在大体积范围内触发点火的实用性。它还将在氯化合物的分解中进行测试，因为它们在化学上与碳氢化合物燃料非常相似。该方法的成功将确保为设计高效、无污染的发动机和焚化炉提供非常有用的技术基础。对能源节约和环境控制的长期关注使得这种方法的发展变得非常重要。
