Defining Occupancy

DC occupancy [math]\equiv \frac{N_{hits}}{N_{evt}}\frac{\Delta t}{t_{sim}}\frac{1}{112}\frac{1}{12}[/math]

where

[math]N_{hits}\equiv [/math]The number of DC wires intersected by primary and secondary events throughout the drift chamber in Region 1

[math]N_{evt} \equiv \phi \times P(interacting)[/math]

[math]\phi \equiv [/math] Number of incident particles on the face of drift chamber per cm^2

[math]\Delta t \equiv [/math] 250 ns: The time needed for events to be read by the electronics within Region 1

[math]t_{sim} \equiv [/math] Time of simulation = [math]\frac{N_{incident}}{I}[/math]
