Ion sources are devices that allow creating ion beams (e.g. argon ions) and to project them outside the device, for example to be further processed by a particle accelerator, or to irradiate materials or biological tissues etc.

The ions are usually created by a plasma inside a cavity filled with a noble gas maintained at low pressure inside the cavity.

So, the cavity cannot have a hole to let the ions get out, otherwise the vacuum would be destroyed. So, by what mean do the ionions get out of the cavity?

In a ion source, how do we make the ions get out of the cavity?
