TGEMS : defined as GEM detector which use thick PCboard (0.4 mm thick) size GEM preamplifiers with hole diameters between 0.5 and 1 mm.
PCboard spacing = 1.5 - 2 mm.

- [math]\displaystyle{ V_{GEM} = 0.103 \times V_{Detector} }[/math]
- [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] voltage is ~[2900V, 5800V] ([1950V, 4000V]) for [math]\displaystyle{ CF_4 }[/math] ([math]\displaystyle{ Ar/CO_2 }[/math]).
