Spin-exchange polarization study at the TRIUMF OPPIS
- TRIUMF, 4004 Wesbrook Mall, Vancouver, B.C. V6T 2A3 (Canada)
The TRIUMF optically pumped polarized ion source (OPPIS) now produces 56 {mu}A H{sup {minus}} ion current and 85% polarization for routine operation and 120 {mu}A and 78% polarization in high current mode. This is a result of the latest ECR primary proton source improvements and optimization of optical pumping efficiency. It has been shown that in a pulsed mode suitable for high energy accelerator applications, it is possible to produce 1--2 mA of polarized H{sup {minus}} current in a charge-exchange OPPIS based on the INR-scheme(1). A possible INR-scheme upgrade to the 10 mA range is discussed. The experimental results on spin-exchange polarization presented in this paper hold promise of polarized H{sup {minus}} current increasing to the 10 mA range.
