Purpose and merit of the simulation including kinds of events being
simulated :

This research is to develop new trigger for the PHENIX experiment.
The trigger is for detecting high momentum muon from W boson decay
using forward muon arm of the PHENIX detector. Measurement of
helicity dependent asymmetry in W production at polarized proton-proton
collisions is the strong approach to understand the spin structure of
the proton. Especially, it reveals polarized sea quark distribution of
the proton, which is one of the major questions in the study of
the proton structure.

We are developing an additional electrical circuit
to the original electronics. The trigger circuit obtain a part of
the signal from the original electronics and provide the trigger
signal for the data taking. The trigger was installed for
north muon arm of the PHENIX detector during last summer and
the data are being collected in ongoing RHIC-Run09. We propose
to keep the DST produced during the run on CCJ disk and
utilize CPU for the analysis to evaluate the trigger performance.
