Question

What is optimum operating voltage in gm counterz?

Answer 1

Explanation:

The optimum operating voltage will be about the middle of the plateau, usually some 150 to 200 volts above the knee of the curve. Set the high voltage to this point and record. The slope S of the plateau of a GM tube serves as a figure of merit for the tube.

Answer 2

Answer:

With neon, the Franck–Hertz voltage interval is 18.7 volts, and an orange glow appears near the grid when 18.7 volts is applied. This glow will move closer to the cathode with increasing accelerating potential, and indicates the locations where electrons have acquired the 18.7 eV required to excite a neon atom.
