Combined plasma-coil optimization algorithms
Sophia A. Henneberg, Stuart R. Hudson, David Pfefferlé +1
Combined plasma-coil optimization approaches for designing stellarators are discussed and a new method for calculating free-boundary equilibria is proposed. Four distinct categorie…
Coulomb collisions in strongly anisotropic plasmas II. Cyclotron cooling in laboratory pair plasmas
Daniel Kennedy, Per Helander
The behaviour of a strongly-magnetized collisional electron-positron plasma which is optically thin to cyclotron radiation is considered, and the distribution functions accessible…
Coulomb collisions in strongly anisotropic plasmas I. Cyclotron cooling in electron-ion plasmas
Daniel Kennedy, Per Helander
The behaviour of a collisional plasma which is optically thin to cyclotron radiation is considered, and the distribution functions accessible to it on the various timescales in the…
Necessary and Sufficient Conditions for Quasisymmetry
Eduardo Rodriguez, Per Helander, Amitava Bhattacharjee
A necessary and sufficient set of conditions for a quasisymmetric magnetic field in the form of constraint equations is derived from first principles. Without any assumption regard…
Available energy of magnetically confined plasmas
Per Helander
The concept of available energy of a collisionless plasma is discussed in the context of magnetic confinement. The available energy quantifies how much of the plasma energy can be…
