Many of the particle detectors developed are gaseous based on ionization.
The semiconductor and scintillation detectors are the most typical and cast-off, but
other, entirely diverse ideologies have also been functional, like Cerenkov light and
transition radiation. Recent detectors in particle physics pool numerous elements in
layers much like an onion. The present chapter is aimed to deliberate the significant
aspects of G. M. Counter (Geiger-Muller Counters), Wilson cloud chamber, Scintillation counter and a semiconductor detector.
Keywords: Counter, Detector, G. M, Particle, Wilson Cloud.
