A drift-kinetic model to describe the plasma dynamics in the scrape-off layerregion of tokamak devices at arbitrary collisionality is derived. Ourformulation is based on a gyroaveraged Lagrangian description of the chargedparticle motion, and the corresponding drift-kinetic Boltzmann equation thatincludes a full Coulomb collision operator. Using a Hermite-Laguerre velocityspace decomposition of the gyroaveraged distribution function, a set ofequations to evolve the coefficients of the expansion is presented. Byevaluating explicitly the moments of the Coulomb collision operator,distribution functions arbitrarily far from equilibrium can be studied atarbitrary collisionalities. A fluid closure in the high-collisionality limit ispresented, and the corresponding fluid equations are compared withpreviously-derived fluid models.
