🧵 This slow-motion video shows the inside of the JET tokamak during a shattered pellet injection (SPI) experiment. Shattered pellet injection is a technique to minimise the impact of disruptions – events where the hot fusion plasma in a tokamak can very rapidly lose its heat and electromagnetic energy on to the structures surrounding it... 1/5

幾秒內	UK Atomic Energy Authority ukaeaofficial	SPI does this by firing a blast of frozen deuterium (heavy hydrogen) and/or neon into the disrupting plasma. A solid frozen deuterium/neon pellet is fired towards the plasma down a tube specially designed to shatter the pellet in to a plume of small pieces just before it arrives at the plasma edges. 2/5

Like the last 10 years, and the 10 years before that etc. (Maybe just go with wind and solar, they’re a lot cheaper and work today) hey, I’m a scientist but sometimes, flogging a dead horse n all that. To say nothing of the cost, which arguably would be better spent on insulating people’s houses.
