  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 $6.9\pm0.5\cdot
10^4\sfrac{atoms}{sec}$ and the total yield was
$3.2\pm0.4\cdot10^{-9}\sfrac{atoms}{deuteron}$. We summarize our methods and
estimates of efficiencies, rates of production and effusion.
