High intensity 11C beams are necessary for the investigation of the formation of 12C via the nuclear reaction 11C(p, γ)12N → 12C + e+ + ν. The production of intense carbon beams on-line is quite challenging due to the thermodynamic properties and

The TRIUMF-ISAC radioactive ion beam facility was designed and constructed to allow irradiation of thick targets with up to 100 \(\upmu \)A proton beam intensities. Since beginning operation in 1998, beam intensities on ISAC targets have progressivel

The present status of the ISAC facility for rare isotopes beams after its first 10 years of operation is presented. Planning for the ISAC facility started in 1985 with the Parksville workshop on radioactive ion beams (Buchmann and D’Auria 1985). It

The production of radioactive ion beams (RIB) from spallation targets by irradiation with a continuous 500 MeV proton beam, has been routine at TRIUMF for several years. Based on the experience with composite refractory carbide targets a procedure fo

On-line targets of silicon carbide have been used to produce radioactive ion beams (RIB) at TRIUMF’s ISAC facility. Surface ionized beams of Li, Na and Al from SiC targets have been delivered to a variety of experiments. While yields of Li and Na r

Many experiments carried out at radioactive beam facilities require the production of intense, isotopically clean and isobar free beams of a particular isotope. At TRIUMF the addition of a resonant ionization laser ion source (TRILIS) enables a multi
