Recent results from the TRIUMF optically pumped polarized ion source

The TRIUMF optically pumped polarized H− ion source has been installed on the TRIUMF cyclotron. Initial results are 0.5 μA dc beam with 43% polarization at 290 MeV. This is expected to be improved upon with normal troubleshooting. A superconducting solenoid to be installed within the next few months will allow a significant further increase in both polarization and beam current.
