Publication Abstract: A first measurement of the inclusive target single-spin asymmetry, Any, has been performed in deep-inelastic scattering of electrons from a 3He target polarized normal to the electron scattering plane. This asymmetry is void of contributions at the Born level, and thus is a direct observable for two-photon physics. The experiment was performed in Hall A at Thomas Jefferson National Accelerator Facility from October 2008 through early February 2009. The measurement is the first from a polarized neutron target. The final overall precision is several times better than previously existing SLAC proton data, and significantly extends the kinematic range over which the asymmetry has been measured. The asymmetry was measured at five kinematic points in the deep inelastic scattering region covering Q2 = 1 - 3 GeV2 and xB = 0.16 to 0.41. The asymmetry varied from 0.006 to 0.071 with astatistical precision at the 10-2 level.
