X5 TEST BEAM preliminary studies

This document outlines preliminary studies focused on TIB and TOB modules, including voltage and PLL scans. It discusses sensor uniformity, normalization of signals and noise, and results from various runs. The effects of high voltage on signal-to-noise ratios (S/N), cluster width, and delay curves are analyzed. Notably, signal normalization methods and their impact on measurements across different configurations and runs are highlighted. Detailed descriptions of data collected, including comments on the studies conducted, are presented alongside key findings.
