Title
(EN) SPARK ABLATION DEVICE
(FR) DISPOSITIF D'ABLATION PAR ÉTINCELLE
Abstract
(EN) A spark ablation device for generating nanoparticles comprising a spark generator; the spark generator comprising first and second electrodes, wherein the spark generator further comprises at least one power source which is arranged to be operative at a first energy level for maintaining a discharge between the first and second electrodes, which power source is arranged for repetitively increasing the energy of the discharge to a predetermined secondary level that is higher than the first energy level for ablating a portion of the electrodes.
(FR) L'invention concerne un dispositif d'ablation par étincelle pour générer des nanoparticules, comprenant un générateur d'étincelle ; le générateur d'étincelle comprenant des première et seconde électrodes, le générateur d'étincelle comprenant en outre au moins une source d'alimentation qui est agencée pour être opérationnelle à un premier niveau d'énergie pour maintenir une décharge entre les première et seconde électrodes, la source d'alimentation étant agencée pour accroître de façon répétitive l'énergie de la décharge à un niveau secondaire prédéterminé qui est supérieur au premier niveau d'énergie pour l'ablation d'une partie des électrodes.
