With the startup of the High-Luminosity Large Hadron Collider (HL-LHC), the Inner Detector (ID) will be replaced with a fully silicon detector known as the ATLAS Inner TracKer (ITk). This new tracking detector is composed of silicon pixel sensors and silicon strips which will extend the tracking detector range up to a pseudorapidity of 4. The demand for a new tracking detector comes as a result of the particle dense collisions produced by HL-LHC. With the increased particle density and radition levels, the success of the ITk requires that it must tolerate the expected dose of radiation while maintaining efficient tracking. Tests have demonstrated that the ITk Pixel detectors' 3D $50\times50\ \mu m^2$ sensors maintains hit efficiency beyond the expected fluence. Additionally, simulations have demonstrated that the ITk, under an average interaction per bunch crossing of $\text{<}\mu\text{>}=200$, will achieve similar tracking efficiency to that of the ID under an average interaction per bunch crossing of $\text{<}\mu\text{>}=38$.
