Proton Accelerator

Proton Accelerator#

A high-energy proton accelerator produces a proton beam with a radius of 0.13 \(\textrm{mm}\). The beam current is 13 \(\rm\mu \rm{A}\) and is constant. The charge density of the beam is \(n = \) 5.44 \( \times 10^{11}\) protons per cubic meter.

Part 1#

What is the current density of the beam?

Answer Section#

Please enter a numeric value.

Part 3#

How much time does it take for \({{params.p}} \times 10^{10}\) protons to be emitted by the accelerator?

Answer Section#

Please enter a numeric value.
