Abstract
Reactions such as 25 Al(p,γ ) 26 Si are the key to understand the production of 26g Al and 26m Al in our galaxy. Experimental results could provide important constraints on nova nucleosynthesis and modelling where 26 Al is believed to be produced. To achieve such measurements, high-intensity and high-purity radioactive beams are required. However, production targets at ISOL-type facilities such as ISAC at TRIUMF produce high-intensity alkali beams by surface ionization on hot transfer tubes hampering the measurement of isotopes of interest. To overcome this issue, an ion source combining a segmented linear radiofrequency quadrupole (RFQ) to a laser ion source is being built. Its main function is to suppress alkali impurities whilst allowing for fast-release of short-live di sotopes. The beam production method, the RFQ/laser ion source and the removal of alkali contaminants are discusse di n this paper.
