+No. of Stations: 4
+First two stations (1,2) are made up of GEM and last two stations (3,4) are made up of RPC.
+Passive material implemented in GEM modules. Ar:CO2 (70:30) is used as active gas. 
+12 mm thick Al plates are used for support and cooling in the GEM modules.
+2 mm thick Aluminum plates are used for support in the RPC modules behind the active area. 10 mm thick Aluminium at the boundaries as the frame.
+Drift and read-out PCBs (copper coated G10 plates) inserted for realistic material budget for both GEM and RPC modules.
