The Geiger-Muller Tube
Beginning of paper
In , particles ionize gas atoms. The tube
contains a gas at low pressure. At one end of the tube is a very thin ”window”
through which charged particles or gamma rays pass. Inside the tube is a copper
cylinder with a negative charge. A rigid wire with a positive charge runs down
the center ....

.... in the circuit. The voltage is amplified and registers the arrival of
a particle by advancing a counter or producing an audible signal, such as a
click. The potential difference across the tube so that the current flow stops.
Thus the tube is ready for the beginning of a new avalanche when another
particle or gamma ray enters it.
