Abstract : A one-dimensional numerical code has been written, which allows the time-dependent simulation of the Child-Langmuir diode and the plasma sheath problem. The model assumes a semi-infinite plasma reservoir from which particles can be emitted into a vacuum region where they can be accelerated or decelerated by means of an external potential on the anode, until they are eventually absorbed by the anode or sent back to the reservoir. Physical results are shown for both the time-independent and the time-dependent cases. Numerical methods are presented for the evaluation of relevant physical quantities. The numerical effects are discussed. (Author)
