41. This research was undertaken on the Mega Ampere Spherical Tokamak ( MAST ) at Culham Centre for Fusion Energy . 42. In 2009 she was awarded a PhD in Plasma Physics ( specialising in fusion energy ) from Imperial College London. 43. In current tokamak ( and other ) magnetic fusion experiments, insufficient fusion energy is produced to maintain the plasma temperature. 44. Breakeven is an important goal in the fusion energy field, but ignition is required for a practical energy producing design. 45. Assuming complete removal of tritium and recycling of 3 He, only 6 % of the fusion energy is carried by neutrons. 46. In 1999, the Princeton lab received $ 63 million in federal funding for continued research in fusion energy and plasma science. 47. This represents a fusion energy gain factor ( or simply " fusion gain " or Q ) of three or four. 48. The laser would also be used to investigate ways to generate nuclear fusion energy and to model the interiors of stars. 49. ITER would be a burning plasma experiment, which is viewed as an important next step in the pursuit of fusion energy . 50. The reactor would be a burning plasma experiment, which is viewed as an important next step in the pursuit of fusion energy .
