Title: Status report of the radioactive ion beam production at TRIUMF (invited)

Abstract

The ISAC radioactive ion beam (RIB) facility has been operational since November 1998. The ISAC Facility at TRIUMF utilizes up to 100 {mu}A proton intensity at 500 MeV from the existing H{sup -} cyclotron to produce RIB using the isotopic separation on-line (ISOL) method. The science programs at ISAC range from nuclear astrophysics to fundamental symmetry. The facility can deliver RIB to the low energy area and a linear accelerator composed of a four-rod radio frequency quadrupole and a linear accelerator can provide beam from A=3 to 30 amu with an energy range from 0.15 to 1.5 A MeV. An accelerator upgrade is underway and will allow us to extend the mass range to A=150 amu and the energy up to 6.5 A MeV. The target/ion source assembly and heavy-ion optics components are located in a shield canyon under 2 m of steel shielding allowing high proton beam intensity on a thick target. At the beginning the production target was operating at 2-5 {mu}A but rapidly the proton beam intensity was raised to 40 {mu}A. Now, we operate up to nearly 100 {mu}A proton beam using the new high power target design equipped with radial fins. While the production targetmore » capabilities have improved quite a lot, from 2 to 100 {mu}A, the ion sources development have not followed the same trend. Since the beginning of ISAC most of the RIB production is done using the surface ion source. A 2.45 GHz electron cyclotron resonance ion source (ECRIS) was built and used on line with moderate success.« less
