Hermes: global plasma edge fluid turbulence simulations
in Plasma Physics and Controlled Fusion
| Description | We have studied turbulence in plasma devices, which is important for predicting how heat and particles are moved around inside high temperature fusion devices. Through experiments and simulations we have made and tested predictions of when plasma becomes turbulent. We have discovered that plasma turbulence is strongly suppressed in expanding magnetic fields, a result which may be important for future experiments. We have developed state-of-the-art models for magnetised plasmas, such as tokamak fusion devices. The enable us to calculate the properties of plasmas to help understand experiments, and to make predictions for machines currently being built. We are currently applying this model to the UK flagship MAST-Upgrade, currently being built at CCFE. |
| Exploitation Route | All code an inputs are publicly available on github (https://github.com/boutproject/hermes). Details of the code have also been published in journals and presented at conferences. |

| Sector | Public |
| PI Contribution | We jointly bid for EUROfusion funding, and carried out a project to validate our respective turbulence simulation codes. |
| Collaborator Contribution | CRPP share many of our interests in developing state-of-the art simulations of tokamak edge turbulence, in order to understand current experiments and predict future experiments. During this year they have provided expertise in a validation technique (MMS), and hosted coordination meetings. |
| Impact | A paper will appear shortly on validation activities in 2014, and we have made another joint bid for EUROfusion funding to continue our successful collaboration. |

| Title | Hermes |
| Description | Hermes is a plasma transport and turbulence modelling code. It includes effects which govern the global structure of the plasma, such as realistic geometry and neutral gas interactions, as well as small-scale turbulence. It is aimed at fully self-consistent simulations of turbulence and transport in current and future magnetised plasma fusion devices. |

| Results and Impact | I gave an invited talk to this conference in Korea, covering work on this grant amongst other topics. The aim was to build links to the South Korean fusion programme. In negotiations we have identified several promising areas of mutual interest and benefit, and made concrete plans to take these forward. |
