The Energy Problem

• In the last two years, growth in Chinese consumption has exceeded the total German consumption

Fusion as a solution

• The amount of lithium contained in a laptop battery, combined with less than half a bathtub of water, will be able to provide enough fusion fuel to supply one person’s energy for 30 years.

This PhD

• Modelling ECE diagnostics at JET using SPECE– Install SPECE code and use it to model JET shots

– Add models of diagnostics onto SPECE

– Install and optimise module into integrated system

• Exploit physics capabilities of method– Reconstruct JET temperature profiles

– Study impact of non-thermal electron distributions in JET

• Study of system for use in ITER– ITER is the next big step for fusion (project unites EU, Japan, Russia, South Korea, India, US and China)

– To be built in Southern France, operational by end of 2018

ITER

• Now is an exciting time to join tokamak fusion research!
