摘要：

A dc discharge in helium has been modeled from electrode to electrode, fully kinetically using a self-consistent electric field and including all the physical processes believed to be important for ions, electrons and neutral atoms. The cathode fall, negative glow, and cathode fall-negative glow boundary develop naturally in the simulation without an internal boundary condition and without breaking the electron energy distribution function in components. Results of the simulation are compared to precise experimental results for the electric field profile, species densities, and average electron energy. Excellent agreement is obtained demonstrating that the physical model used is both correct and complete.
