[Isotope-prod] Possible opportunity

[Pavel Degtiarenko]

Dear Hari,

George and I just had a brief discussion, and we think that might be a 
good opportunity to produce some real Cu-67 here for use at VCU. Last 
week we discussed purchasing some Cu-67 for tests of the VCU separation 
and spectroscopy equipment. By irradiation the natural Ga sample here at 
18.5 MeV like we did last time, we can produce isotopically clean Cu-67 
in gallium right here. After that we can measure its quantity reliably 
in the target without the separation (there will be no Ga-67 to 
interfere at this energy), then may be even try to do the test of the 
chemical process and see how much can be extracted. That would be up to 
VCU to decide what to do with the irradiated sample and what would be 
the reasonable Cu-67 activity for them to start the tests. On our side, 
we would like to have better prepared experiment, including the 
availability of the harps to measure beam position and energy precisely.

As far as Cu-64 is concerned, we think that might be a second priority, 
because we already had a test at 56 MeV and reliably did not see it. Our 
present understanding is that the FLUKA simulation produces too much of 
Cu-64. This issue is being addressed to the FLUKA collaboration; we hope 
they will be interested to resolve it soon.

Best regards,
Pavel
