The TRIUMF H/sup -/ cyclotron has been operating with 80% availability over the last year. Two proton beams are extracted simultaneously with energies which may be varied independently between 183 and 520 MeV, while the ratio of their intensities may be adjusted from unity to 1/5000. Beam intensities up to 10 ..mu..A are being scheduled for regular operation, and 50 ..mu..A were achieved during tests. The intensity of the +-78% polarized beam from the ''Lamb shift'' ion source is 30 nA (extracted). The external beams have an energy spread of 1.5 MeV and emittances of approximately 3..pi.. mm-mrad; the microscopic and macroscopic duty factors are 11% (5/43 nsec) and 100%, respectively. The secondary beam lines operational include a muon channel, a slow and stopping pion line and a biomedical ..pi../sup -/ line. Monokinetic fast neutrons, 40-70% polarized, are also available from a liquid deuterium target. It is planned to increase the extracted beam current in stages to 100 ..mu..A by the end of 1977. Work is also progressing on additional beam lines, a 180 kW beam dump and thermal neutron source, a medium resolution proton spectrometer, and adding third harmonic flat-topping to the rf to reduce the energy spread to 0.1 MeV.
