[Isotope-prod] 18.5 MeV test - preliminary results

[George Kharashvili]

The first look at the gallium activation test suggests that we produced ~4500 Bq of Cu-67. 
Irradiation was done using 18.5 MeV beam on 1mm W radiator for 1 hour at average current of 2.5 microA, or 46 W-h. We had predicted 7000 Bq production in a 50 W-h irradiation. There are several differences between the model and irradiation, so I need to rerun the model and do a little more detailed analysis of the sample.
More to follow during the next couple of days.
