Query: First measurement of the $^{10}{\rm B}(\alpha,n)^{13}{\rm N}$ reaction
  in an inertial confinement fusion implosion at the National Ignition Facility   We report the first measurement of the $^{10}{\rm B}(\alpha,n)^{13}{\rm N}$
reaction in a polar-direct-drive exploding pusher (PDXP) at the National
Ignition Facility (NIF). The target is composed of a 65/35atomic%
deuterium-tritium fill surrounded by a roughly 30$\mu$m thick Beryllium
ablator. The inner portion of the Beryllium ablator is doped with 10atomic% of
10-Boron. Radiation-hydrodynamics calculations were performed in 1D to optimize
both the remaining Boron rho-R and the DT neutron yield. A charged-particle
transport post-processor has been developed to study $\alpha$-induced reactions
on the ablator material. Results indicate a large 13-Nitrogen production from
$\alpha$-induced reactions on 10-Boron, measurable by the Radiochemical
Analysis of Gaseous Samples (RAGS) system at the NIF. The PDXP target
N201115-001-999 was successfully fielded on the NIF, and Nitrogen from the
$^{10}{\rm B}(\alpha,n)^{13}{\rm N}$ reaction was measured. The $^{13}\rm N$
production yield, as well as the DT neutron yield, were however lower than
expected, likely due to the asymmetry of the implosion.
