Modified High Speed Geiger Counter Circuit
H. Victor Neher, William H. Pickering · Physical Review · 1938
Although the speed of the circuit designed by Neher(1) is quite satisfactory, it suffers from the disadvantages of requiring insulation for the cylinder and shielding if two or more Geiger counters are used to count coincidences. Also, the capacity of the cylinder for large counters introduces a longer reaction time. With the circuit to be described the cylinder of the counter is grounded.
