A linear accelerator produces a pulsed beam of electrons. The current is 1.6 A for the 0.1-μs duration of each pulse.

(a) How many electrons are accelerated in each pulse?

(b) What is the average current of the beam if there are 1000 pulses per second?

(c) If each electron acquires an energy of 400 MeV, what is the average power output of the accelerator?

(d) What is the peak power output?

(e) What fraction of the time is the accelerator actually accelerating electrons? (This is called the duty factor of the accelerator.)
