The gluons' Gluons spin contribution to proton spin is an important the key aspect for understanding the proton spin structure. It can be probed by the double helicity asymmetry of {pi}0 production in polarized p+p collisions. During the longitudinally polarized proton run in 2006 PHENIX collected substantial data at {radical}s=62.4 GeV and {radical}s=200 GeV. In 2006 PHENIX commissioned a new electromagnetic calorimeter, the Muon Piston Calorimeter (MPC), located in the forward rapidity rapidities region. This calorimeter allows to significantly improves the PHENIX acceptance. In this report the MPC feasibility of the MPC for longitudinal double spin asymmetry studies is discussed.
