The TRIUMF KAON Factory

TRIUMF is Canada's National Meson Facility. The TRIUMF site is hidden in a rain forest on the campus of the University of British Columbia in Vancouver, British Columbia. TRIUMF's current research program uses a cyclotron to accelerate 100 micro-amperes of protons to 500 MeV. TRIUMF has proposed to the Canadian Federal and Provincial Governments that TRIUMF be upgraded to 100 micro-amperes at 30 GeV. To house theproposed 5-ring accelerator complex the TRIUMF site will expand from 10 acres to about 70 acres. Negative hydrogen ions will be extracted from the cyclotron at 452 MeV and transferred to a booster complex. The booster complex will house a 452 MeV proton storage ring (A ring) and a 50 Hz 0.452-3 GeV synchrotron (B ring). The circumference of these rings is 215 meters. A figure shows the Booster Tunnel cross-section, and that the intention is to stack the rings one above the other. To isolate the storage ring from any vibration caused by the very fast cycling synchrotron, the A ring magnets will have separate supports from the B ring. After the Booster synchrotron has accelerated the protons to 3 GeV, they are transferred to a 3 GeV proton storage ring (C ring) in the main accelerator tunnel. The main tunnel houses the C, D, and E rings. The D ring is a 10 Hz 3-30 GeV synchrotron and the E ring is an extender/storage ring to allow slow extraction at 30 GeV. These rings have a circumference of approximately 1.1 km. The C ring will be mounted directly above the D ring, while the E ring will be offset horizontally to protect the C and D rings from slow extraction losses. Again they will try to isolate the storage rings from any vibration generated by the fast cycling synchrotron
