Description:
<jats:p>An approximation technique for computing the space charge limited current between electrodes of unusual and complicated geometry that cannot be treated rigorously is discussed and applied to several electrode systems involving both cylindrical and sphreical emitters. This method was originally suggested by Matricon and Trouvé and by O'Neill. All that is required is a knowledge of the electrostatic capacitance of the system concerned. Many electrode systems of practical importance which were heretofore not susceptible of calculation are amenable to this technique.</jats:p>
