We Have Pics"},"content":{"rendered":"

Nuclear fusion may always be ten years away, but the technological breakthroughs aiming to get us there are already here\u2014including an imaging technique that vividly shows why fusion is said to harness the energy of the stars.<\/p>\n

A recent release<\/a> from UK-based startup Tokamak Energy presents an unprecedentedly colorful image of a fusion reaction, captured using a high-speed color camera at 16,000 frames per second. The mesmerizing footage is a treat for the eyes, but the different colors each represent valuable information for fusion researchers investigating the efficacy of the reactor.<\/p>\n

Plasma is better in colour! Watch one of our latest #plasma<\/a> pulses in our ST40 tokamak, filmed using our new high-speed colour camera at an incredible 16,000 frames per second.<\/p>\n

Each pulse lasts around a fifth of a second. What you\u2019re seeing is mostly visible light from the\u2026 pic.twitter.com\/jWKmcl0tEx<\/a><\/p>\n

For example, the bright pink glow represents the edge of the hydrogen plasma. The green streaks come from lithium ions that trace the path of the plasma around the tokamak, a donut-shaped instrument that confines hot plasma for fusion reactions. The plasma\u2019s core is \u201ctoo hot to emit visible light,\u201d the company explained, but the other color signals offer invaluable information on how different fusion ingredients interact with one another.<\/p>\n

Decoding the colors of fusion <\/p>\n

Simply, nuclear fusion combines two lightweight atoms\u2014most often deuterium and tritium, two hydrogen isotopes\u2014to generate massive amounts of energy. Unlike fission, which splits heavy atoms, fusion doesn\u2019t leave behind harmful, radioactive waste.<\/p>\n

Fusion would be the ideal alternative to fossil fuels\u2014if we can get it to scale commercially, that is. Although the field has made significant strides<\/a> over the years, the general understanding is that practical fusion energy is still years away.<\/p>\n

Again, fusion\u2019s goal is to replicate stellar energy on Earth, which means fusion experiments involve many extreme conditions that are notoriously difficult to investigate. As with any technology, researchers want to understand how and where things can go wrong\u2014especially when dealing with volatile material like the super-hot plasma confined inside a reactor.<\/p>\n

Inching toward better performance <\/p>\n

Naturally, physicists have been hard at work finding a workaround<\/a>. The new footage was part of an investigation into X-point radiator regimes, an approach that seeks to gain better control of plasma flow to \u201creduce wear without compromising performance,\u201d according to Tokamak Energy.<\/p>\n

\u201cThe color camera is especially helpful for experiments like these,\u201d said Laura Zhang, a plasma physicist with Tokamak Energy, in the release. \u201cIt helps us immediately identify whether the gaseous impurities we\u2019re introducing are radiating at the expected place and whether lithium powders are penetrating to the plasma core.\u201d<\/p>\n

\u201cThis work is advancing our understanding of plasma behavior as we scale up to energy-producing fusion devices,\u201d added the researchers. \u201cThe addition of color imaging is already providing valuable insights into how materials interact within the plasma.\u201d<\/p>\n
