[labnetwork] Aluminimum source crucible suggestions

Hi Cliff,


We had the same issue with Al in graphite crucibles.


Al deposition in intermetallic crucibles has been working perfectly for us.


Regards,

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
