[labnetwork] Installation of CNT and Graphene systems in shared labs?

[John Shott]

Labnetwork community:

Our faculty advisory board has asked us (the Stanford Nanofabrication 
Facility) to plan for the installation of a carbon nanotube (CNT) 
furnace and a graphene reactor in our clean room.  Specifically, they 
are looking at the FirstNano EasyTube 3000 and the Aixtron Black Magic 
4" Pro, respectively.

I'm interested if anyone has experiences to share with equipment of this 
type in a shared clean room environment.  Specifically, is there 
anything special that you do to protect the person loading/unloading 
samples ... and other nearby folks ... from possible particle exposure 
during normal operations of these tools?  Also, are there any special 
precautions that you take for the staff members working on either the 
reaction chamber, the vacuum system, or downstream abatement systems?  
Finally, are there anything that you do specially to protect the outside 
environment from possible particle generation?

Note: our EasyTube 3000 should be outfitted with the FirstNano 
EasyExhaust Burn Box.  It is not obvious that the Aixtron Black Magic in 
the graphene reactor has any sort of included burn box ... although, by 
default, if we did nothing else, the pump exhaust would still be routed 
to our laboratory-wide water scrubber.

Thanks for your consideration,

John
