Abstract
ATLAS Tile Calorimeter (TileCal) is an experimental tool used in particle Physics for measuring the energy of particles produced in high-energy collisions. Its performance and stability depend on careful observation and analysis of several operating parameters, temperature data being especially important. This study presents the continuous approach to the temperature variation of the ATLAS TileCal drawers, extracted from the Detector Control System (DCS). The TileCal DCS continuously monitors all the hardware and infrastructure for each subsystem. The Tile-in-One (TiO) tool is used to visualize and analyse this temperature study. The TiO is a collection of small, independent web tools called plugins. Plugins assess the quality of data and conditions for ATLAS TileCal. A comparative analysis is done to determine the development of the leaks or improvements achieved in the cooling system and the stable values of the temperature in the drawers. The work aims to continuously study the variation of temperature in the module over a short period of time using the TiO platform and display it to a user in a friendly and intuitive manner using contemporary web technologies. The plugin ensure that temperature fluctuations remain within a specified 0.2 ℃ threshold, as deviations beyond this range significantly impact TileCal drawer components such as PMT gain variation. The study shows that the temperature
variation is maintained at ±0.2 ℃.
