  The TRIUMF cyclotron was originally conceived for several proton beams extracted simultaneously at different energies. Recent operation includes a 500 MeV beam up to150 μA for meson users, a 500 MeV beam up to 80 μA for rare isotope production, and a 100 MeV beam up to 70μA for medical isotopes. The extraction of an additional high intensity proton beam, at an energy between 450 and 500 MeV for ISAC has now been given priority. With the rare ions produced from the existing and future primary beam lines, we will be able to operate two of the existing experimental areas simultaneously. Upgrading the cyclotron for higher intensity is in progress. A necessary goal for ISAC is the extraction of both primary proton beams with stability better than 1% to allow the highest possible temperatures to be reliably maintained at the ion production targets. A successful solution implemented for the existing primary ISAC beam has been simulated to be adaptable for both primary beams, given the particular angular separation between the two strippers in the cyclotron. Progress on intensity and stability studies and the layout of the extraction system will be presented.
