| 41. | Fusion reactions power the sun and stars.
|
| 42. | The easiest fusion reaction to achieve is found in a 50 50 mixture of tritium and deuterium.
|
| 43. | Over the decades, scientists have spent billions of dollars to mimic the sun's hot-fusion reactions on earth.
|
| 44. | Cross sections for many fusion reactions were measured ( mainly in the 1970s ) using particle beams.
|
| 45. | The result is an object massive enough to undergo nuclear fusion reactions _ a star, like the Sun.
|
| 46. | Fusion reactions combine light plasma state.
|
| 47. | The other basic type of nuclear weapon produces a large proportion of its energy in nuclear fusion reactions.
|
| 48. | US experiments soon demonstrated the same neutrons, although temperature measurements suggested these could not be from fusion reactions.
|
| 49. | This was used in the 1970s and 1980s to study the cross sections of high energy fusion reactions.
|
| 50. | In 1977 construction began for 6 metre ( 20 foot ) superconducting electromagnets intended to control fusion reactions.
