在欧米茄激光设备上，观察到磁化激光驱动惯性约束聚变内爆中离子温度和聚变产率的提高。在极驱动结构下，用10 atm D(2)气体填充的球形CH靶进行了内爆。一个80kg的磁场被嵌入目标中，随后被内爆的导电等离子体捕获和压缩。由于热点磁化，电子径向热损失被抑制，离子温度和中子产率分别提高了15%和30%。
Enhancement of the ion temperature and fusion yield has been observed in magnetized laser-driven inertial confinement fusion implosions on the OMEGA Laser Facility. A spherical CH target with a 10 atm D(2) gas fill was imploded in a polar-drive configuration. A magnetic field of 80 kG was embedded in the target and was subsequently trapped and compressed by the imploding conductive plasma. As a result of the hot-spot magnetization, the electron radial heat losses were suppressed and the observed ion temperature and neutron yield were enhanced by 15% and 30%, respectively.
