A cyclotron is accelerating proton, where the applied magnetic field is $2 T$ and the potential gap is $100 keV$ . To acquire kinetic energy of $20 MeV$ , the number of turns, the proton has to move between the dees is

Options:

Answer:

Solution:

Energy gained in one movement across the gap is $100 keV$

Therefore the energy gained in one turn is $200 keV$

$N = \frac{20 M e V}{200 keV} = \frac{20 \times 1 0^{6}}{200 \times 1 0^{3}} = 100$
