Hi there,
Sorry for bothering. I have a question about E-beam heating on STM machine.
We currently plan to use E-beam heating at the machine but it seems like the
machine has only radiative heating function. Now we need to modify the
power supply and filament a little bit to realize E-beam heating. The way is
to float the current power supply and bias the filament. Does anyone | M*********m

connected to case ground and secondary completely floated. Not sure what you
are asking for.
