“…The ISAC is an online based post-accelerator which uses 500 MeV protons of up to 100 µA from the TRIUMF cyclotron [2] to bombard the isotope production target. The radioactive ions are extracted from an ion source at an energy up to 60 keV for the single charged ions.…”

The design of a radiation hard ECR source for the ISAC radioactive beam facility has been completed. The ion source with its 0-60 kV extraction system is coupled to the radioactive isotope production target via a small transfer tube. For a typical ISAC target the copper coils of the ECR source will be exposed to a dose rate of about 10 5 Gy/h for a 100 µA-500 MeV incident proton beam. The whole assembly is located beneath a 2 m thick steel shielding structure. Construction details of the target-ion source system and auxiliary equipment are described. The source will be tested at the TRIUMF test bench during the second half of 2001 and will be installed in the ISAC facility by the middle of 2002.

“…TRIUMF's space charge limit has been estimated to be E 500 pA with 100 kV of dee voltage, which comfortably exceeds our 400 pA goal. Stripping losses have been reduced by installing an auxiliary rfbooster cavity to increase the energy gain per turn above 450 MeV where most of the stripping loss occurs [7]. This allows us to increase the 500 MeV extracted beam from 170 to 250 pA.…”

A new series of experiments (mainly astrophysics) hegan at TRIUMF in July 2001 when the ISAC-I linear accelerator began delivering up to 1.5 MeV/u radioactive ion beams (RIB) to users. A superconducting linear accelerator extending the RIB energy to 6.5 MeV/u has recently been approved and is now being constructed (ISAC-11). Record RIB intensities are being achieved from different target ion sources with a primary incident proton beam of 500 MeV, up to 50 pA intensity. This will later be increased to 100 pA, compatibly with target acceptance. Furthermore. an additional 100 pA extracted proton beam is being considered for simultaneous (RIB) production from a second target-ion source system. This would significantly enhance the research potential of the Iahoratory. Four simultaneous high-intensity extracted beams would therefore.he required for a total maximum cyclotron accelerated current of about 400 pA. Recently we have been able to deliver 300 pA to the existing three high intensity beam lines at 90% duty cycle. The cw delivery of beam was limited only by the presently available external beam dump capacity. In this paper we will review the present operational experience at 200/250 pA, the future plans for intensity upgrade to 350/400 pA, and the intrinsic factors limiting the total accelerated intensity beyond400 pA.
