迈向先进燃料聚变:稠密等离子体中电子、离子能量>100 keV
Towards Advanced-fuel Fusion: Electron, Ion Energy >100 keV in a Dense Plasma
摘要:
使用先进燃料的受控聚变需要在致密等离子体中平均电子和离子能量超过100 keV(相当于11亿K)。我们已经满足了这一要求,并证明了电子和离子的能量超过100千电子伏,在一个紧凑和廉价的密集等离子体聚焦装置。我们已经在等离子体“热点”或等离子体团中实现了这一点,在我们最好的结果中,密度约束时间能量积为5.0 × 1015 keVsec/cm 3,这是任何聚变实验的记录。我们用X射线探测器测量了电子能量,最终证明硬X射线是由热点产生的。
英文摘要:
Controlled fusion with advanced fuels requires average electron and ion energies above 100 keV (equivalent to 1.1 billion K) in a dense plasma. We have met this requirement and demonstrated electron and ion energies over 100 keV in a compact and inexpensive dense plasma focus device. We have achieved this in plasma "hot spots" or plasmoids that, in our best results, had a density-confinement-time-energy product of 5.0 x1015 keVsec/cm3, a record for any fusion experiment. We measured the electron energies with an X-ray detector instrument that demonstrated conclusively that the hard X-rays were generated by the hot spots.
