The high intensity radioactive beam facility at TRIUMF

Construction has begun on ISAC, a radioactive ion beam and accelerator facility which utilizes the ISOL production method. A five year budget for this new radioactive beam facility at TRIUMF was approved in June 1995. ISAC includes: a new building with 5000 m2 of floor space, a proton beam-line with adequate shielding to transport up to 100 μA at 500 MeV from the TRIUMF cyclotron to two target/ion-source stations, remote handling facilities for the targets, a high-resolution mass-separator, linear accelerators and experimental facilities. The ISAC design for the target/ion source station permits the production of nuclei far from stability over a large isotopic range with high luminosity. The accelerator system includes an RFQ and a DTL yielding final energies variable from 0.15 - 1.5 MeV/u. The buildings are now complete and the installation and commissioning of the injection beam-line, target facility and the RFQ are underway. This paper outlines the ISAC project status. (author)
