The ion kinetic energy spectrum in a pulsed vacuum arc is presented. The arc current lasts for 35 ms (HAFW), having a peak value of 500 A. A retarding field analyzer system, (consisting in an aperture plate, a charge selecting grid and an energy analyzer collector electrode) and Langmuir probes are employed. The plasma density inside the retarding field analyzer is obtained, and it is shown that the spatial charge between the grid-collector region has some influence on the low energy part of the ion spectrum.
