Abstract : The 3 causes of delays in Geiger counters are discussed. They include the electron transit time formed in the initial ionizing event from its place of origin to the avalanche region, the time for the discharge to spread along the length of the wire, and the time required for the positive ion sheath to drift far enough from the central wire to permit formation of a large enough pulse for detection. Various experimenters are cited with detailed comparisons of their experimental procedures and results. A discussion of the long transit lags due to negative ions is included.
