We propose the study of an electronic sensor allowing the collection of sprays in free space. The detector consists of three elements: a photodiode situated in the center of the structure to which is applied a bias voltage, an aluminum ring which referenced to a voltage higher than that of the photodiode and an insulating material disk (polyvinyl chloride). The total size of the structure is fixed by the diameter of the disk of insulating material. The electrostatic field created by this sensor has to allow an optimization of the collection of sprays. To obtain the biggest volume of possible detection, it’s necessary to optimize dimensions of the various elements of the structure, geometries and voltages.
