【 摘 要 】

A slow positron beam is being built in the Hebrew University, the Slow POsitron faciliTy (SPOT). In Israel, the beam will introduce a new tool for both fundamental and applied research. Here we present the design process of the beam, where the leading goals are safety and high efficiency, with a flexible choice of the positron source. The challenges in the design of a moderator unit, based on frozen Neon, the pre-accelerator section and the full beam-line were addressed by simulation programs using various packages: COMSOL, SIMION and GEANT4. First measurements in SPOT are expected within a year.
