~(23)Ne production at SARAF-I

摘要

In this article, we present a measurement of flow rate, yield and effusion time of a ~(23)Ne production and transport system. We used an accelerator-driven Li(d,n) neutron source to produce neutrons up to 20 MeV. The radioactive atoms were produced by a ~(23)Na(n,p) reaction at a NaCl target. Later, the atoms were diffused out from the NaCl crystals and effused from the production chamber via a 10 m hose to a measurement cell and their decay products were detected using High Purity Germanium (HPGe) and plastic scintillator detectors. The resulting flow rate was 6.9±0.7·10~4 atoms/sec and the total yield was 3.2±0.6·10~(-9) atoms/deuteron. We summarize our methods and estimates of efficiencies, rates of production and effusion.
