[math]V_{GEM} = 0.103 \times V_{Detector}[/math]
.

[math]V_{GEM}[/math] is between ~[300V, 600V] for [math]CF_4[/math] and for [math]Ar/CO_2[/math] it is [200V, 370V];
[math]V_{Detector}[/math] voltage is ~[2900V, 5800V] ([1950V, 4000V]) for [math]CF_4[/math] ([math]Ar/CO_2[/math]).

PCboard spacing = 1.5 - 2 mm.
