[Isotope-prod] Target system REquirements

[George Neil]

The less manipulation of the target that is required the happier I would 
be....

But I agree we need to see if that attachment happens.   If it does then 
perhaps we can offer the Cu a material it would prefer to attach to that 
would eliminate the need for chemically processing the gallium..
