Electron-positron plasma physics
- Of fundamental interest to basic plasma physics and fusion
- Instead of m+/m- ~ 1837 or larger, m+/m- = 1
- Basic questions need to be answered
- Will turbulence and transport be similar to electron-ion plasmas?
- Drift wave instabilities are driven by the vast mass difference between ions and electrons - should be absent in e+e- plasma
- Gyroradius (isotope) scalings from theory and numerics are contradicted in experiments - ?1837 rather than ?3
- Nonlinear dynamics and saturation mechanisms may be completely different
- Of fundamental interest to astrophysics
- Annihilation rates are low, ?annihilation~ hours at Te=10 eV
