• FAIR is a facility, which will serve a large part of the nuclear physics community (and beyond):
- Nuclear structure Radioactive beams- Dense Matter Relativistic ion beams- Hadronic Matter Antiprotons, (polarized)
- Atomic physics- Plasma physics
• FAIR will need a significant fraction of the available man-power and money in the years to come:
1 G€ 10 000 man-years = 100 “man” for 100 years
or (1000 x 10)
• FAIR will have a long lead-time (construction, no physics) staging (3 phases)
