GEM and GMX Endcap Diameters
Detector sizes designated as Standard are placed in the designated endcap size. For detector sizes designated as Optional, the endcap size must be specified by adding the Endcap Model (-xx) to the Detector Model (e.g., GEM25-76 or GMX25P4-70).

Endcap Model  (mm) -70 -76 -83 -95 -108
Endcap Diameter (in) 2.75 3.00 3.25 3.75 4.25
Standard  (eff.) 0-20%   50-55% 70-110% 120-150%
Optional   (eff.) 25-35% 25-45% 25-45% & 60-65% 60-65%  

Cryostat and Dewar DIMENSIONS ARE SUBJECT TO CHANGE.
If these specifications are critical to your application, please contact the factory.
