Quasi-elastic scattering on $^{12}$C$(e,e'p)$ was measured in Hall C atJefferson Lab for space-like 4-momentum transfer squared $Q^2$ in the range of8--14.2\,(GeV/$c$)$^2$ with proton momenta up to 8.3\,GeV/$c$. The experimentwas carried out in the upgraded Hall C at Jefferson Lab. It used the existinghigh momentum spectrometer and the new super high momentum spectrometer todetect the scattered electrons and protons in coincidence. The nucleartransparency was extracted as the ratio of the measured yield to the yieldcalculated in the plane wave impulse approximation. Additionally, thetransparency of the $1s_{1/2}$ and $1p_{3/2}$ shell protons in $^{12}$C wasextracted, and the asymmetry of the missing momentum distribution was examinedfor hints of the quantum chromodynamics prediction of Color Transparency. Allof these results were found to be consistent with traditional nuclear physicsand inconsistent with the onset of Color Transparency.
