Advances in Photonic and Metamaterial RF structures | |
|
||
| Interest in the use of novel electromagnetic media for particle acceleration and EM wave generation is growing. In part driven by the possibility to overcome limiting issues in conventional technologies, and offer novel ways in which to accelerate particles. Photonic media can confine a single EM frequency whilst forcing all other frequencies to propagate away, significantly reducing the long range wakefield of a structure. The novel dispersion curves of metamaterials define unique particle-wave interactions enabling compact inverse Cherenkov acceleration. In this presentation we examine the use of photonic media and metamaterials for RF generation and particle acceleration. We review the physical processes and defining length scales, energy exchange mechanisms, examining the advantages offered by these media and the issues that can arise from their use. | ||

| The potential for using thorium as an alternative or supplement for uranium in fission power generation has long been recognised, with growing concerns over nuclear waste, safety and proliferation. Thorium may be used in solid fuel form, or in molten salt systems. In some approaches the fuel can incorporate components from spent nuclear fuel (minor actinides, plutonium) to also serve a transmutation function. We consider the benefits and drawbacks of using an accelerator driven subcritical system, for both solid fuel and molten salt cases, in particular addressing the power and reliability requirements of the accelerator. We outline the research that will be necessary to lead to an informed choice. | ||
