1.   In all experiments on toroidal discharges neutrons have been observed in about the numbers to be expected if thermonuclear reactions were proceeding.

2.   Kurchatov visited Harwell and suggested that he might give a lecture on Soviet work into thermonuclear reactions in gas discharges.

3.   The objective was to use a relatively small fission device to trigger-off a thermonuclear reaction of arbitrarily large yield.

4.   If fusion were achieved, a microbubble could be expected to radiate neutrons, nuclear particles produced by thermonuclear reactions.

5.   Nuclear fusion relies on the bonding of nuclei to create a thermonuclear reaction similar to that of the sun.

6.   So energetic is this imaginary machine that using it would be like harnessing a thermonuclear reaction.

7.   The stadium-sized laser is designed to let scientists study thermonuclear reactions without full-scale weapons testing.
