Electronic counter: Geiger counter principle

Principle of Geiger electronic counter

1, Geiger counter, consisting of a hollow metal cylinder C and a metal wire W, W and C electrical insulation and parallel to the axis. C is equipped with a low pressure of about 50 of argon (about 1/15 atmospheric pressure), plus the amount of potential difference between W and C, so that w is at a higher C potential, but still not enough to make argon discharge. At this time if the particles or other radiation by a thin window a into, will make cylinder argon ionization, free electrons will be taken charged wire W to attract.

2, while electronic toward w accelerating, it will with other argon atom collisions and hit more electronic, so sequentially produced more electrons flow to the w mobile, and produce a short pulse current, through appropriate amplification device G, the pulse current can produce the familiar answer sound, or promote the counter and actuarial into C number of radiation particles.
