[Isotope-prod] Target system REquirements

[Pavel Degtiarenko]

Hi All,

I think we have a couple of major R&D questions that should be addressed 
in this project.

The first one, related to Physics: we need the cross sections for 
Ga-71(gamma,alpha)Cu-67 at least with some reasonable accuracy of 
20-30%. All technical solutions will depend on that directly.

The second one, related to the target R&D: the question of the 
attachment of Cu-67 to the Tungsten walls. Is there a chance that a 
large portion of Cu-67 produced in Gallium during the run will alloy 
itself with Tungsten and never come out. Is there any chemical solution 
that could be used to wash/rinse the target after irradiation to extract 
Copper (but keep Tungsten)?

Best regards,
Pavel
