摘要：

The temporal evolution of the plasma sheath in small cylindrical bores and planar gaps is calculated for zero-rise-time voltage pulses. The ions are modeled as a cold, collisionless fluid, and the problem is reduced to the solution of two coupled, first-order, ordinary differential equations. These equations are solved analytically for the planar case, and numerically for the cylindrical case. The maximum ion impact energies are 50% and 36.8% of the maximum potential drop in the planar and cylindrical cases, respectively. Ion impact energy decreases with the square of the radius of the bore.
