[math]\displaystyle{ V_{GEM} = 0.103 \times V_{Detector} }[/math]
.
[math]\displaystyle{ V_{GEM} }[/math] is between ~[300V, 600V] for [math]\displaystyle{ CF_4 }[/math] and for [math]\displaystyle{ Ar/CO_2 }[/math] it is [200V, 370V];
[math]\displaystyle{ V_{Detector} }[/math] -
PCboard spacing = 1.5 - 2 mm.
