Hi All,<br>
<br>
I think we have a couple of major R&D questions that should be
addressed in this project.<br>
<br>
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.<br>
<br>
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)?<br>
<br>
Best regards,<br>
Pavel<br>
