Název v původním jazyce

Effect of grounding and isolation of the target on the emissive properties of laser-produced plasma

Popis výsledku v původním jazyce

During laser ablation, the escaping electrons generate a net positive charge at the target surface. Depending on whether the target is grounded or isolated from the vacuum chamber, either this positive charge is neutralized by the current flowing from the ground or generates a voltage on the isolated target corresponding to its capacitance. Under certain experimental conditions, it can be expected that this charge can retroactively affect not only the expansion velocity of the emitted ions and their number, but also the total number of escaped electrons. In this work, we deal with ion emission and measuring the voltage arisen on an isolated target or the current of electrons flowing between the ground and a grounded target. For the first time, this made it possible to estimate the ratio of the number of electrons released from plasma to the number of electrons stopped by a potential barrier.
