Yes, great job everyone. Imagine the possibilities if the LERF
could be funded as a "Test Facility". We could do similar tests 9
ways till Sunday.<br>

<b>Subject: </b>[Isotope-prod] 18.5 MeV test - preliminary
results<br>
</div>
<div><br>
</div>
<div data-marker="__QUOTED_TEXT__">The first look at the gallium
activation test suggests that we produced ~4500 Bq of Cu-67. <br>
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.<br>
More to follow during the next couple of days.<br>
