Optimizing Stellarators for Turbulent Transport [PDF]
, 2010 Up to now, the term "transport-optimized" stellarators has meant optimized to minimize neoclassical transport, while the task of also mitigating turbulent transport, usually the dominant transport channel in such designs, has not been addressed, due to ...

New Classes of Quasi-helically Symmetric Stellarators
, 2010 New classes of quasi-helically symmetric stellarators with aspect ratios ≤ 10 have been found which are stable to the perturbation of magnetohydrodynamic modes at plasma pressures of practical interest.

Contributions to Plasma Physics, Volume 60, Issue 5-6, June-July 2020., 2020 Abstract Advanced divertor configurations modify the magnetic geometry of the divertor to achieve a combination of strong magnetic flux expansion, increased connection length and higher divertor volume—to improve detachment stability, neutral/impurity confinement and heat‐channel broadening.

Symposium - International Astronomical Union, 1986 We have been monitoring the CaII H and K emission in late-type giant stars using the Mt Wilson 60-inch telescope. It is a continuation of work that Olin Wilson began almost 20 years ago. As a result not only have starspot cycles been detected (equivalent to the solar sunspot cycle), but rotation periods have now been measured.

Stability in straight stellarators [PDF]
, 1981 The stability of the straight stellarator against localized interchange modes is investigated employing the Mercier-Greene-Johnson criterion. Critical values of ..beta.. are obtained both numerically and analytically. The conclusion is that for classical

Some problems in stellarator reactor design
, 1981 This thesis examines theoretically the potential of the plasma confinement device known as a Stellarator as a fusion reactor. Chapter one contains a survey of the requirements for nuclear fusion to take place in a device employing magnetic confincment ...

Fusion Science and Technology, 2004 Stellarators are toroidal devices where the required rotational transform of the magnetic field lines is generated by external field coils and not via an induced net toroidal plasma current. This confinement scheme has the advantages that, in principle, steady-state plasma operation is possible and that it does not have to brace itself against ...
