Question

in the cyclotron, why the frequency is independent to the radius is a practical advantage of the cyclotron?

Answer 1

just think- you need to switch the polarity of the voltage, which is independent of the radius.now all u need is a ac voltage of desired frequency...else u ud have to change the frequency of ac voltage also,which would have been a real headache..

Answer 2

I really dont understand what you said.:d

Answer 3

k i will break it up...
now..the velocity of electron will increase in a cyclotron...now where is this extra kinetic energy coming from?

Answer 4

electric field between the dees

Answer 5

exactly.now can u recall that this electric field will need to be switched to opposite direction after every half circle rotation of the electron? (after each entry through a single dee)

Answer 6

so what will it do with the frequency?

Answer 7

now we cant just change the electric field anyway we like can we...we have to do it such that it always increase the speed of electron and not decelerate it..
at a the E field should be towards right but at bottom it should be toward left to push electron along its direction of motion.agreed?
