Abstract
Some different time measurement methods have been presented for similar signals with the same trigger that one can choose by considering signal conditions. Finding the best time measurement method for the output signals from the UFSD (Ultra Fast Silicon Detectors) is our goal because we wanted to use these sensors to detect protons in the proton therapy system to treat cancerous tumors. Some different methods include Constant Fraction Discriminator (CFD), Cross-Correlation (CC), and Time over Threshold (TOT) by different data. These kinds of data include Data from Weightfield2 which is a UFSD signal simulator, Data from simulated signals in practice inside the laboratory, and experiment data, which are real data from the UFSD test in front of a Pico laser beam. Several programs in MATLAB software have been written and run to analyze and compare the different methods. The results are shown that CFD is the best method for time measurement finally
