A permanent magnet lens has been designed to be a non-powered alternative to solenoids for low energy beam transport. The lens consists of a single ring of 12 sectors, each sector with poles directed inward. This forms an axial field that reverses sign at the midpoint, somewhat like two opposing short solenoids. It is similar to the Iwashita lens* but consists of only one ring, not two. A prototype lens optimized to decrease the magnetic material required while also reducing aberration, has been built and tested for a 25 keV H-minus beam. Emittance figures measured downstream of the lens are compared with theory. * Y. Iwashita, "Axial Magnetic Field Lens with Permanent Magnet", Proc. PAC 1993, p.3154.

	This paper describes the preliminary results of a high brightness ion source developed at TRIUMF, which is capable of producing a negative hydrogen ion beam (H⁻) of up to 5 mA of direct current. A 1.7 mm.mrad and 5 mm.mrad emittance(rms) is achieved for 500 uA and for 1 mA H-, respectively. Characteristics as well as a brief description regarding extraction issues of the source to date are also presented.

This paper describes the preliminary results of a high brightness ion source developed at TRIUMF, which is capable of producing a negative hydrogen ion beam (H⁻) of up to 5 mA of direct current. A 1.7 mm.mrad and 5 mm.mrad emittance(rms) is achieved for 500 uA and for 1 mA H-, respectively. Characteristics as well as a brief description regarding extraction issues of the source to date are also presented.
