Ionization chamber and GM tube

  1. Feb 15, 2010 #1
    1. The problem statement, all variables and given/known data

    What are the difference between ionization chamber and GM tube in structure which make them have different functions?

    3. The attempt at a solution

    Higher voltage is applied to GM tube so that electron avalanche can occur.
    Then I wonder that
    if higher voltage is applied to ionization chamber, it can function as a GM tube.

    The difference is...
    ionization chamber is connected to galvanometer and operate at normal gas pressure
    while GM tube is connected to a counter and operate at low pressure

    Is it?
