Radiation transport simulations are key to designing safe and efficient neutron instruments at spallation sources such as ISIS. The radiation transport codes are being developed continually to utilise modern high performance computing facilities to enable us to tackle larger problems within a reasonable timeframe. The two main methods for radiation transport are Monte Carlo methods and deterministic methods. Deterministic methods discretise space, energy and angle to solve the transport equations usually on a regular structured grid, which can scale well on 100-100,000 computer processors. This project will investigate a new deterministic transport code currently under development at Imperial College to enable it to simulate neutron instrument shielding. The code aims to use an unstructured mesh to define the geometry and achieve similar levels of scaling on high performance computers. The project will aim develop a module for the new deterministic code to extend the current source options and apply it to a relevant facility problem. This will involve writing computer code to specify the source, integrating it with the main program, developing tests using UK leading high performance computing and analysing the data.
The student will learn about:
- radiation transport codes,
- contribution to leading research
- nuclear data,
- CAD and meshing,
- high performance computing,
- data analysis and computer programming.
