1. St4 Prop Tube Mapping 05/15/2011 Ming Liu This is a mapping diagram for St-4 prop tubes Facing a module/FEM: – ECL Channels counted from right (1) – to left(16) (16,15,14,…3,2,1) – Within a plane: viewing modules standing at IP, Vertical tubes: modules IDs are counted from left (1) to right (9) Horizontal tubes: top (1) to bottom (9) Naming scheme – Plane(1 or 2)/moudle-orientation (H or V) and number (1 to 9)/chan (1 to 16) – P1H2C8 = Plane-1, 2 nd Horizontal tubes, chan-8 FEM Card 16, 15, … 3, 2, 1
