Commissioning of the EXOTIC Beam line

A new beam line is now fully operational at Laboratori Nazionali di Legnaro (LNL) TANDEM/ALPI accelerator for the in-flight production of light low-energy Radioactive Nuclear Beams (RNBs). The RNBs are produced by inverse kinematics reactions induced by heavy ions, such as 17O and 6Li, on 1H and 3He gas targets. The beam line has a large solid angle acceptance ( Δ Ω = 10 msr ) and a high rejection capability of spurious beams due to the combined action of magnetic rigidity and velocity filtering. A very pure (100%) and high intensity ( 3.6 × 10 6 pps ) 17 F 9 + secondary beam at E lab = 86 ± 1 MeV has been produced and used for experiments. A 8 B 5 + beam at E lab = 33 MeV , with a production rate of ∼ 2 × 10 3 pps , is presently under commissioning.
