The current produced is the total charge that circulates the particle accelerator per unit time.
We calculate this by the equation:
is the number of protons, 
is the charge per proton, 
is the velocity of each proton, and 
is the radius of the particle accelerator.
Using the given current, we then solve for the velocity:
The current produced is the total charge that circulates the particle accelerator per unit time.
We calculate this by the equation:
Using the given current, we then solve for the velocity:
