Collisional effects on the Weibel instability
Journal Article

· Phys. Fluids; (United States)
The effects of electron Rutherford scattering on the Weibel instability are investigated using the implicit plasma simulation code Ve-smcapsn-smcapsu-smcapss-smcaps (J. Comput. Phys. 46, 271 (1982); 63, 434 (1986)). Collisions decrease the Weibel growth rate below the collisionless value, in agreement initially with simple linear theory. Likewise, collisions decrease the saturation level, in agreement with a magnetic trapping mechanism. When the collision rate exceeds the collisionless Weibel growth rate, the instability is suppressed altogether. The results provide benchmarks for analysis of proposed short-wavelength laser-fusion schemes.
