Three collections of plots:
•
Plots per target nuclide, e.g. a-Cu065.pdf
•
Plots per reaction channel, e.g. n-MT004.pdf (all n,n’
reactions)

All plots for a projectile, e.g. p.pdf

•
Optimize the best reaction path, via p,

The higher the proton energy:
-
The higher the yield
-
The lower the specific activity

Simultaneous development:
•
Improve TENDL by TALYS parameter
adjustment + adoption of evaluated libraries
(IAEA medical)
•
Develop interface for medical isotope production
–
Fill the medical portal with ANY reaction
–
Automatic optimization
–
Graphical interface for projectile, target, energy,
accelerator power, etc.

Iphone or Android App?
–
Other ideas?
Thank you!
