SUMMARY

The discussion centers on the feasibility of using neutral beam accelerators for achieving practical fusion, specifically referencing the SIGFE experiment at the University of Wisconsin, Madison. The experiment failed to produce fusion, instead generating neutrons through Fe(D,2n) spallation. Participants debated the necessity of ionizing deuterium atoms for acceleration, the potential of electrohydrodynamic generators, and the advantages of the Polywell WB-6 device over traditional Tokamak designs. The conversation concluded that while the Polywell shows promise, significant challenges remain in achieving the necessary ion densities for practical fusion.

PREREQUISITES
  • Understanding of neutral beam injection techniques
  • Familiarity with fusion concepts, particularly deuterium and tritium reactions
  • Knowledge of electrohydrodynamics and its applications
  • Awareness of the Polywell WB-6 fusion device and its operational principles
NEXT STEPS
  • Research the operational principles of the Polywell WB-6 fusion device
  • Study the challenges of achieving high ion densities in fusion reactions
  • Explore the role of electrohydrodynamic generators in fusion technology
  • Investigate advancements in neutral beam injection for plasma heating
USEFUL FOR

Researchers, physicists, and engineers involved in fusion energy development, particularly those focused on alternative fusion methods and accelerator technologies.

If this is for real why is not used to generate power?Could you give some ref. on such experiments?

Hi Stanley, I found this link on Ion Beam Fusion at Berkeley National Laboratory, University of California. Very promising work by the look of things!

Because it doesn't generate net power. It uses more than it produces.
