Abstract

Germanium-68 (T1/2 = 270.8 d) serves as a generator parent for the short-lived ⁶⁸Ga (67.6 min) positron emitter utilized in PET. ⁶⁸Ge can be produced in accelerator through the reactions ⁶⁹Ga(p,2n) or with natural gallium ^natGa(p,*) ⁶⁸Ge (natural gallium consist of 60% ⁶⁹Ga). SARAF (Soreq Applied Research Accelerator Facility) is based on a high intensity proton/deuteron superconducting linear accelerator currently in construction at Soreq NRC. The low melting point of gallium poses a challenge for target design. In order to contain the target material and separate it from the evacuated beam line a thin metallic foil is used. SARAF target development group works for several years on development of target for high power accelerators. One of the target designs has been modified to enable ⁶⁸Ge production by the high current proton beam of SARAF. This is almost one order of magnitude higher than current state of the art. The design has undergone a comprehensive test program with a high-power electron-gun and the low energy high current Phase-I SARAF accelerator beam. The first target model used FIAVAR foil to separate the liquid Gallium from the beam line vacuum. A second model is using a SS316L foil which has been found to have similar strength.
