Description
The design of the ATLAS Inner Tracker (ITk), which will replace the Inner Detector of ATLAS at CERN, is nearly complete. Following the long shutdown after Run 3, this crucial component for the High-Luminosity era will be installed. However, reliable environmental monitoring tools are required to measure temperature and humidity, ensuring consistent data quality throughout the lifespan of the ITk. This need is addressed through the use of novel titanium oxide (TiO$_2$)-coated Long Period Grating (LPG) sensors, which are currently in full production. In this study, the relationship between coating thickness and LPG sensitivity to both radiation and humidity is investigated. The resulting sensitivity measurements can be used to optimise coating thickness for sensor applications in high radiation environments, including nuclear industries and space exploration. In particular, the results are used to optimise thickness and optimal sensor placement for LPGs being used within the ITk, specifically: ten-layer sensors are recommended for lower-radiation regions, while eight-layer sensors are better suited for higher-radiation areas.
