摘要:

Appropriately restricted,the normalized integral of a stationary process asymptotically approaches a Gaussian distribution, but the expectation of the exponential function of the unnormalized integral does not have the value anticipated from this fact. An example is given, applicable to turbulence.

摘要:

Efficiency and optimum angle of incidence of combined resonant and collisional absorption of laser light are found by numerical simulation and an economical extension of ray tracing to be moderately insensitive to pulse width and peak power.

摘要:

Neoclassical transport coefficients are derived for a multi‐species plasma in a mixed regime, with several banana‐plateau species,a, and several Pfirsch–Schlu¨ter species,z. It is assumed thatma≪mz, but the masses are otherwise arbitrary.

摘要:

Improved particle trajectories are employed to treat the adiabatic or Maxwell–Boltzmann response of a plasma in order to choose between contradictory prescriptions for obtaining the nonlinear dispersion relation from the linear one.

摘要:

A short (∼0.5 msec) localized vertical magnetic field (∼200 G) is used to extract runaway electrons from a tokamak plasma without affecting the thermal component of the plasma. This effect is documented with measurements of the hard x‐ray and suprathermal microwave emission from the torus.
