Stellarator plasma chamber helps develop nuclear fusion.(EMERGING TECHNOLOGY)(Brief article)
Advanced Materials & Processes, May, 2007
Current plasma research builds on two types of magnetic plasma confinement devices, tokamaks and stellarators, report researchers at the University of Wisconsin at Madison. They have developed a combination instrument called the HSX, which aims to merge the best properties of both by giving a more stable stellarator the confinement of a more energetically efficient tokamak.
Tokamaks, the current leader in the fusion race, are powered by plasma currents, which provide part of the magnetic field that confines the plasma. However, they are susceptible to "disruptions." Stellarators do not have currents, and therefore no disruptions, but they tend to lose energy at a high rate, known as transport. The external magnetic coils that generate the plasma-confining...
