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.
TGEM Detector HV setting
[2]Media:Development_of_Tracking_Detectors_with_industrially_produced_GEM_Foils.pdf
is between ~[300V, 600V] for and for it is [200V, 370V];
voltage is ~[2900V, 5800V] ([1950V, 4000V]) for ().
PCboard spacing = 1.5 - 2 mm.
