Dear Moema There seem to be cleaning and leakage problem. please check Zafar To: pvd_coatings@yahoogroups.com From: moema_m@... Date: Mon, 16 Nov 2009...
To be more gentle and uniform on the heating you might try to defocus the e-beam so that it heats a larger area and relies less on moving the beam around. ...

Isolate the copper coils and attach 13,56 rf to the coils. using a control leak, vent air back into the chamber to a pressure od 1.0 to 2.0 x 10-4 evaporate...

Hello, We have a sever adhesion problem with the deposition of 0.5um Al film on stainless steel ferule by E gun. Is there any way to increase the adhesion?...
Hi Zhuo, CAB's answer is correct (defocus the beam). Also you can try decreasing the voltage on the beam, I find less than 7.5kV is better for SiO2 and other...
Does anybody have experience with e-beam evaporated ZnO:Al thin films? I know they are deposited mainly by sputtering and pyrolysis, but I heard that some...
hi you can't avoid cavity effect(hole drilling) while evaporation of sio2 by EB gun.Try to evaporate it with higher rate(>10A/s).Disassociation of Sio2 during...

I agree with Mr.Bishop recommendations and would like just to add a little bit more. If you have a good programmable e-beam sweeper, defocus beam over material...
SiO2 heats in a very uneven way. It is a subliming material, meaning it transitions in evaporation from a solid state - directly to a gas state. It never...
Hello, SiO2 is a subliming material. A stationary beam position will 'drill a hole' at the center. An XY sweep at high frequencies is required during...
