الملخص	Cherenkov detection exploits the emission of electromagnetic radiation when a charged particle travels through a medium faster than light travels in that same medium. This enables precise particle identification and mass measurement through analysis of Cherenkov light patterns, forming a cornerstone technology in modern high-energy physics detectors.	Time-of-Flight (ToF) particle identification measures the time taken for a particle to travel a known distance, enabling determination of the particle's velocity and mass. This complementary technique to Cherenkov and ionization energy loss provides robust particle separation across wide momentum ranges in modern detectors.
