MRPC Spacial Resolution, Beam Position Detected by GEM System (3 GEM Chambers).

X-Axis : ΔX (cm)

Y-Axis:  No. of Events

Note: For MODULE #1, strip 02 has a better spacial resolution than strip 03, due to center of beam-point lies in the area of strip 02. For MODULE #2, beam center is closer to the gap between strip 02 & 03.

         MODULE #1 strip width ~ 3.0cm;     MODULE #2 strip width ~ 2.5 cm.

         GEM spacial resolution < 0.01cm (See here);
