Measurements of Forward Jet Production in Polarized pp Collisions at   \sqrt{s}=500 GeV
  The AnDY project at RHIC was proposed to measure the analyzing power for Drell-Yan production. Test runs took place during polarized proton operations of RHIC in 2011 and 2012 with a model of the AnDY apparatus in place. In total, an integrated luminosity of 9 pb^-1 with beam polarization of 50% was sampled. The primary detector components were a hadron calorimeter (HCal) that spanned the pseudorapidity interval 2.4 < \eta < 4.0 and a small electromagnetic calorimeter (ECal). Basic goals for AnDY test running were to establish the impact of a third interaction region on RHIC performance and to demonstrate HCal calibration. Energy scale of HCal was established using neutral pion reconstruction and checked with hadronic response. In addition, data with a trigger based on HCal energy sum were taken to study jet events. First measurements of analyzing power in the forward jet production are reported.
