A proposal (P07?013) to measure the target normal single spin asymmetry A^n_N in inclusive deep-inelastic n-uparrow (e, e') reaction with a vertically polarized 3He target has been conditionally approved to run during Jefferson Lab?s Hall A neutron transversity experiments (E06?010) and (E06?011) in summer 2008. The expected accuracy of this measurement is delta-A^n_N = 2?4 × 10?4 at four different values of the invariant mass. The normal spin asymmetry in DIS probes helicity?flip amplitudes at the quark level related to effects beyond the leading-twist picture of DIS. Preparations for this experiment will be discussed including the development of a secondary luminosity monitor for Hall A.
