Discussion and news on advancements in the field of nuclear fusion energy and related technologies.
Nuclear Fusion on Reddit
Focused on advancements in the field of nuclear fusion.
Submissions should be related to nuclear fusion or plasma physics as currently understood by the scientific community.
Nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide together at a very high speed and form a new nucleus. For light elements like hydrogen or helium the fused nucleus weights less than the sum of the original nucleus. The missing mass is released as energy in accordance with Einstein's mass-energy equivalence equations. Fusion is the process that powers active or "main sequence" stars.
Current mainstream approaches include:
Magnetic confinement, used in tokamak, spheromak and stellarator designs
Inertial confinement, used at the National Ignition Facility
Electrostatic confinement, used by the fusor and Polywell devices
Magnetized target fusion and Magneto-Inertial fusion, hybrid approaches used by General Fusion and Helion Energy

(Permit #B2309-015 Issued: 2024/3/15) Two-story 1200 SF prebuilt office space inside Ursa. 1st floor-tritium lab, 2nd floor-8 office pods & 3 phone booths. This will allow them to set up and test their isotope separation and tritium storage systems.
Inspections of their mechanical systems for the tritium lab exhaust (M2408-079) and the tritium stack (M2407-008) have been moved to Monday December 9.
Electrical rough-in inspection (E2407-059) is scheduled for Friday December 6. Electrical plans include: 10 new rectifiers 330kW each, new HVAC loads of 635kVA, 760kVA, and 268kVA and new equipment loads of 330kVA, 335kVA, 295kVA, and 300kVA.
Permit extensions this week for both the capacitor racks (B2312-034) and the rectifier racks (B2405-074.)
Other outstanding permits are for filling in the pit (B2407-044) used for quartz tube production and for the modular parts of their shield wall and roof (B2304-083) which might be the best indicator of Polaris being ready for operation.
I was thinking the rotating core of the flywheel could be a rare earth magnet, and the plasma could be confined near the edge just using regular magnets if the temperature and pressure is kept low. The mass of the plasma compared to the mass of the magnetic flywheel would be low, and the rotation of the magnets might help keep the plasma confined. Is anyone working with plasma that is at lower relative temperatures? Can we talk about plasma related technologies, or is this strictly for doing fusion with plasma?

Although being criticized, ENN is still saying using hot ion mode to reduce Bremsstrahlung radiation in its papers

Last I checked (2022) about 50% of the Rare Earth's came from China. Thet are actually not rare, but the US DOD is still trying to stand up domestic suppliers in Texas and elsewhere.
MOST US fusion firms need the HTS wire and that means using rare earth's.
What do you guys think?
Just curious if anyone would like to ask anything related to Fusion power? Currently doing a PhD in plasma physics and need some fresh air from Reddit 😁 If that's not allowed in this sub I will delete the post
Edit: many interesting questions here ☺️ but I am nowhere near expert in the field so I will just call it a discussion and hopefully breaking some information barriers
Hi everyone,
I’m currently studying Engineering Physics, and I’m deeply passionate about plasma physics, fusion, and related applications. I’m seeking research opportunities, internships, or jobs in these fields that are open to international students.
I have experience with numerical simulations, data analysis, and programming in Python and C. I'm also currently learning C++ and parallel computing to further enhance my technical skills.
If you know of any programs, institutions, or projects I could explore, I’d greatly appreciate your suggestions or guidance.
Thanks in advance for your help!
