The forward spectrometer upgrade of the PHENIX detector aims to add capabilities at forward rapidities to: probe nucleon structure
through W production and promptphotons in polarized p + p, study nucleon structure in nuclei at high parton densities in p
+ A collisions through the measurement of γ and π
0 in the forward region, greatly extend the acceptance for high
p
T γ-jet measurements (jet tomography) in A + A, and increase our capabilities to measure the production quarkonium states by
giving sensitivity to the χ
c
through the J/ψ + γ channel.
Key words RHIC - PHENIX - muon trigger - nosecone calorimeter - forward upgrade
