IMPORTANT
From time to time, the gallium emitter has to be regenerated by heating. The heating pro-
cedure removes the gallium oxide which has been created during operation or during
longer breaks.
In general, it is recommended that you activate the automatic heating function. This will ensure
that the ion source is heated automatically if required.
