I  remember that this type of e-beam evaporator has an integrated flux monitor which can be used for understanding the deposition rate. You can establish a good relationship between the deposition rate and the flux.

 [surface science 81] Ge-evaporation

Petra,
 
When I start to evaporate a new material, I find it useful to look up the vapour pressure tables to give me an idea of the temperature I need for a reasonable evaporation time. Kurt Lesker provides a very useful table for purpose. Ge is at http://www.lesker.com/newweb/deposition_materials/MaterialDeposition2.cfm?pgid=0

Dear All,
we want to evaporate Ge from an Omicron EFM 3 electron beam evaporator with
a W-crucible. Unfortunately we do not have a QCM on this chamber and are for
geometric reasons unable to mount one for the measurement of rates. Have any
of you the power-deposition rate relation for Ge evaporations? Or a few
hints as to the evaporation conditions for at least a few rates?
kind regards, Petra
