Beam commissioning and first operation of the ISAC DTL at TRIUMF

The post-accelerator for the ISAC radioactive beam facility combines a 35.4 MHz RFQ and a variable energy 106 MHz DTL. The ISAC DTL is designed to accelerate ions with 3 /spl les/ A/q /spl les/ 6 to energies fully variable from 0.153 to 1.53 MeV/u. The unique separated function design allows efficient room-temperature acceleration and full energy variability with no degradation in beam quality. The first stable beams were accelerated in the DTL in Dec. 2000 with full commissioning in the first months of 2001. Test results with stable beams will be reported and compared with beam simulation results. In addition the initial operating experience with stable beam delivery is reported.
