RECENT PROGRESS AT TRIUMF

ISAC, a new facility for accelerating intense ion beams of unstable nucleii is under construction at TRIUMF. The ra-dioactive nucleii will be produced by up to 100 A of 500 MeV protons impinging on one of two target/ion-source stations located in an underground vault. Singly-charged ion beams will be transported at energies up to 60 keV to a high-acceptance, high-resolution mass analyser by electro-static ion optics. Following mass selection the beam is fur-ther transported vertically to grade level and then horizon-tally to either a low-energy experimental area or to a sys-tem of linear accelerators consisting of an RFQ and a DTL. The beam out of the DTL, will have energy continuously variable from 0.15 to 1.5 AMeV. The facility is now be-ing constructed. A new high intensity extraction beam line from the cyclotron is being installed, and the 500 MeV pro-ton beam has already been extracted, simultaneously with the other high intensity proton beam dedicated to meson production. Commissioning of a grade level portion of the LEBT (using a stable off-line ion source), of a prebuncher, and of the front end of the RFQ, has now begun. The sched-ule calls for first experiments at low energy, using the new target station, to take place before the end of 1998. Other TRIUMF facility progress, including new records for the OPPIS high intensity beams, will also be reported
