[labnetwork] Aluminimum source crucible suggestions

[Clifford F Knollenberg]

Hi All,


We've been having crucible cracking issues with out Al e-beam evaporation source.  In short it cracks its crucible after just a few uses.  This wasn't so bad when it happened ever 4-5 months, but not its happening about every week or two.  I've tried a variety of crucibles, had the most luck with carbon crucible.  Is there anything else out there we should be trying?


Cheers,


Cliff
