  The Thomas Jefferson National Accelerator Facility (JLab) has undertaken the
12 GeV Upgrade to double the accelerating energy of its electron beam. This
attracts many interesting proposals to probe the quark-gluon nature of nuclear
matter at higher energy, therefore a new set of equipment is required.
Experimental Hall C of JLab has planned to construct a new Super High Momentum
Spectrometer (SHMS) to replace the existing Short Orbit Spectrometer (SOS). The
University of Regina is assigned to construct the Heavy Gas \v{C}erenkov (HGC)
Detector as part of the SHMS focal plane detectors. This detector will be used
as critical component to provide reliable pion/Kaon separation between 3-11
GeV/c central momenta in the SHMS experimental program. In this thesis, we will
report the design, quality control studies and simulated expected performances
of the HGC detector.
