High power targets for ISOL Radioactive Ion Beam facility

The ISAC Radioactive Ion Beams (RIB) facility is operational since November 1998. The facility utilizes the Isotopic Separation On Line (ISOL) method to produce the RIB. The new ISAC facility at TRIUMF utilizes up to 100 muA of proton at 500 MeV from the existing H(-)cyclotron. In 2000 the laboratory was approved to extend the mass range from 60 to 150 and the energy range from 1.5 to 6.5 A*MeV. At the beginning of ISAC operation the proton beam intensity was limited I to 40 muA on foil targets and to I to 15 muA on compound target. The development of new kind of target allows us to run routinely to 50 muA even on compound targets, such as Nb, Ta, SiC, TiC and ZrC.
