Abstract
Intense radioactive beams of 15O are required in order to study the high temperatures of the CNO cycle via reactions on radioactive isotopes such as 15O(α,γ)19Ne, which is a key breakout reaction for the rp-process in stars. We have proposed a target that will operate at 500 MeV and 100 μA proton beam by making use of the 16O(p,pn)15O reaction. A water target 20 cm in length will generate approximately 18.5 TBq (500 Ci) of 15O at equilibrium which is equivalent to 3×1015 atoms of 15O, of which 5–10% would be in the form of O2. One major advantage is that the target can operate at ambient temperatures.
