Description and experimental validation of a new PEA signal processing concept

This paper deals with a new method of PEA signal processing used for space materials. The aim of this new approach of deconvolution technique is first to obtain a charge density with an optimized spatial resolution and second to have an estimated charge density without handle any parameters. This new method is compared with the current PEA signal processing widely developed in the literature. After a brief description of the both methods, an experimental comparison is realized with irradiated materials. Results show an enhancement of the spreading of charges at vicinity of electrodes.
