The single spin asymmetry for inclusive direct photon production has been measured using a polarized proton beam of 200 GeV/c with an unpolarized proton target at −0.15<x F <0.15 and 2.5<p T <3.1 GeV/c at Fermilab. The measurement was done using lead glass calorimeters and the photon detectors which surround the fiducial area fo the calorimeters. Background rejection has been done using the surrounding photon detectors. The single spin asymmetry, A N , for the direct photon production is consistent with zero within experimental uncertainty.
