PSW#2331 : Approaching Fusion Fuel Breakeven with Lasers: National Ignition Fac

The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory conducts inertially confined fusion research using lasers, deuterium (D) and tritium (T). If the plasma created by the lasers can be confined for a sufficiently long period of time causing DT fusion reactions, self-heating caused by the alpha particles from the fusion reactions will accelerate until the process runs away and the plasma ignites in a self-sustaining burn.

This talk will cover work using the new "high-foot" pulse-shape implosion that presently holds the record for fusion performance on the NIF. High-foot implosions are the first facility based fusion experiments to generate more energy from fusion than was invested in the fusion fuel. In these experiments, the yield was amplified by the alpha-particle self-heating process by more than ~2X. While much needs to be done to reach ignition, these new results are encouraging.

    very good and sobering talk about the history of the NIF, current activities of the facility and it's incredible technology- and also the applications and spin offs from their work. I asked one of the speakers about any interest in their work by those studying stellar structure for example and he indicated that there is something called Laboratory Astrophysics, where those who are interested in understanding stellar phenomena, can come and work at the facility.

    This group sounds super interesting. My mum is a gynaecologist and my dad owns oil and gas business in India. Me and my brother decided to come to USA and pursue our destiny much to my parents ire. I didn't for one second aim or fathom that I would own a business or much less be a govt contractor. I blame it all on Cupid. Love hit me like a train and made me who I am today. I had plans but, God had his own plan for me. This journey has been spiritually, professionally, and personally enlightening and extremely humbling. My goal in joining this group is to give and take the knowledge we learned, and, grow to be a better person and of course bring any knowledge that will help me grow my business. And hopefully I can help you all as well. Looking forward to meeting you all and having a mutually beneficial and successful relationship with this group. God Bless!
