Nose-Cone Calorimeter: upgrade of PHENIX detector

PHENIX experiment at RHIC is efficient at measuring processes involving rare probes, but has limited acceptance in azimuth and pseudorapidity ($\eta$). The Nose Cone Calorimeter (NCC), a W-Si sampling calorimeter in the region of 0.9\,$<\eta<$\,3, is one of the upgrades which will dramatically increase coverage in azimuth and pseudorapidity. The NCC will expand PHENIX's precision measurements of electromagnetic probes in $\eta$, reconstruct jets, and enhance triggering capabilities. It will significantly contribute to measurements of $\gamma$-jets, quarkonia, and low-$x$ nuclear structure functions. Details of the detector design, performance, and a sample of the physics topics which will benefit from the NCC, will be discussed.
