This talk presented the magnetic confinement experiments from a different angle, i.e. as laboratory sources which allow the study of various problems in such fields as atomic physics and astrophysics.Tokamak and magnetic mirror plasmas have properties which make them particularly suitable for basic atomic physics experiments; they are stable over long intervals of time and have wide ranges of electrom densities and temperatures. Also, models on which electron density and temperature diagnostics are based in astrophysical research can be checked since these quantities are accurately measured by independent non-spectroscopic methods.

Scale Length

Ideally, binary-collision algorithms conserve kinetic momentum and energy. In practice, the finite size of collision cells and the finite difference in the particle locations affect the conservation properties. In the present work, we investigate numerically how the accuracy of these algorithms is affected when the size of collision cells is large compared with gradient scale length of the background plasma, a parameter essential in full- $f$ fusion plasma simulations. Additionally, we discuss implications for the conserved quantities in drift-kinetic formulations when fluctuating magnetic and electric fields are present: we suggest how the accuracy of the algorithms could potentially be improved with minor modifications.
