What’s New

Pre-register before 1 June 2022 for this year's ITER International School on the topic of "ITER Plasma Scenarios and Control."

This in-person event will be held from 25 to 29 July 2022 at the University of California San Diego, hosted by the U.S. Burning Plasma Organization, the ITER Organization, UC San Diego, and General Atomics.

Most attendees will be graduate students, post-doctoral researchers, and early career faculty and research staff working in fields relevant to the ITER program. Although the agenda will focus on topics of scenarios and control, attendees are not required to be working in these subfields. All nationalities, whether representing an ITER Member or not, are welcome.

To register, see this webpage.

The virtual tour of ITER construction has been updated with 360° photos from April 2022. Enter the main ITER plant buildings, fly over the worksite, and plunge 30 metres into the ITER Tokamak pit to see what has changed since the last update in September 2021.

Fusion can theoretically be achieved by several combinations of light elements such as hydrogen, helium or boron. However, in the present state of technology, the only fusion within our reach at industrial level is that of deuterium (D) and tritium (T), both isotopes of hydrogen. DT fusion however has one downside—it generates highly energetic neutrons that activate and alter the structures they bombard. (The good side of fusion neutrons is that they will be used to breed tritium from lithium inside the machine).

For decades, fusion physicists have pursued what is sometimes referred to as the "Holy Grail" of fusion: the fusion combinations that involve helium-3, which, instead of generating neutrons like in DT fusion, produce highly energetic protons. Advantages: no material activation or alteration and, protons being charged particles, the possibility of direct electricity generation (they can be manipulated by electric and magnetic fields). Downside: helium-3, which abounds on the Moon (hence the renewed interest for lunar exploration) is exceedingly rare on Earth.

Now, scientists at the University of California San Diego have discovered evidence that helium-3 could be much more abundant on Earth than previously known.

Led by Benjamin Birner, a postdoctoral scholar in geosciences, the team is developing tools and measurement methods to quantify the puzzling increase of helium-3 in the atmosphere, and understand where it could be coming from.

We might not need to go to the Moon, after all, to mine the fuels for second or third-generation fusion power plants.
