They have to prepare a tiny pellet of tritium at 4 degrees Kelvin and stick it inside this big butt chamber. The resultant output of the fusion energy exceeds the total energy in the the X-rays. It doesn't exceed the energy it takes to generate them, but with enough of a constant fuel source they could achieve it. But figuring that out is much further down the road.
