Imagine the current passing through the collider is 1 picoAmp.
Using the information below, compute the area of the tunnel through which the particles travel inside the collider.
Remember that the individual ions passing through the collider have a charge of +79e, and actually travel at about 99.995% the speed of light. You may approximate that there is roughly 1 gold ion per cubic meter of volume within the detector.
Please express your answer for area in terms of square centimeters.
