TRIUMF Facility

At the TRIUMF cyclotron facility, a beam of negatively charged hydrogen ions are injected at the center of the cyclotron and accelerated to a maximum energy of 520 MeV. These hydrogen ions are stripped of their electrons using carbon foils, producing the proton beam. This proton beam, produced with an intensity of $\sim$140 $\mu$A, is extracted from the accelerator and transported through several beam lines. In beamline BL1A in the meson hall, this beam passes through two secondary production targets, including a 10-cm Beryllium target (T2) producing pions, electrons and muons. The cyclotron has a typical macroscopic duty factor of 98% with an RF (radio frequency) of 23.0055 MHz, producing a beam burst 2-4 ns long every 43 ns (26).
