Abstract :
A secondary beam of radioactive 17F was produced at the ATLAS accelerator and delivered to an experimental target station with an intensity of as much as 5.105 ions/s for use in the research program. Beams of 17F were produced via the p(17O,17F)n or d(16O,17F)n reactions by bombarding a gas-filled cell with up to 300 pnA beams of 17O or 16O from the ATLAS superconducting linac. The gas target, with HAVAR windows, was maintained at pressures as high as 500 Torr. The beam quality was dominated by small-angle scattering in the gas cell windows, by the reaction kinematics and beamline acceptance. Detailed beam parameters are presented. Plans for relocation of the target to allow improved capture efficiency and acceleration or de-acceleration of the secondary beam will also be discussed
