What is the cyclotron frequency of the orbit?
In the outer radiation belt at synchronous altitudes (∼6.6RE geocentric) for example, the electron cyclotron frequency is ∼ 1 kHz, the bounce period for 40 keV electrons is ∼ 1 s, and the drift period is ∼2 hours.
What are the factors on which the cyclotron frequency depends?
Solution : The cyclotron frequency depends upon (i) the magnetic induction and (ii) the specific charge (the ratio charge/mass) of the charged particles.
On which of the following the cyclotron frequency does not depend?
The frequency of a charge circulating iside the dees of a cyclotron does not depend upon the speed of the charge.
What happens to the cyclotron frequency of a charged particle if its speed doubles?
They are never the same. What happens to the CYCLOTRON FREQUENCY of a charged particle if its speed doubles? It triples.
What is the cyclotron frequency write down the equation?
frequency `= omega = (2pi)/(T) = (Bq)/(m)`. (ii) A cyclotron works only when the frequency of the revolution of particle is equal to the frequency of oscillation. `:. ` Mass of proton and deutron are different `(m_(3) = 2m_(P))` and `v alpha = 1/(m)`.
Does velocity affect cyclotron frequency?
It is notable that the cyclotron frequency is independent of the radius and velocity and therefore independent of the particle’s kinetic energy; all particles with the same charge-to-mass ratio rotate around magnetic field lines with the same frequency.
What are the uses of cyclotron frequency?
Beams from cyclotrons can be used in particle therapy to treat cancer. Ion beams from cyclotrons can be used, as in proton therapy, to penetrate the body and kill tumors by radiation damage, while minimizing damage to healthy tissue along their path.
What is the resonance condition in a cyclotron?
In cyclotron the frequency of the revolution of charged particle, that is f=2πRV, will be equal to frequency of the ac voltage source in resonance condition.
Which of the following Cannot be accelerated by cyclotron?
A neutron cannot be accelerated by a cyclotron, because cyclotron can accelerate only the charged particle and neutron is not a charged particle.
When a charged particles move perpendicular to a magnetic field then?
(1), when a charged particle moves perpendicular to the uniform magnetic field, the magnetic force will act perpendicular to the velocity at every instant which makes the particle move in a circular path with constant velocity v. Thus, the magnitude of velocity remains same, but the direction changes.
What will happen to the motion of charged particle if frequency of alternating voltage is doubled?
If the frequency is doubled, the charge will be accelerated at alternate cycles and there will not be change in orbit radius.
What do you mean by cyclotron frequency explain in detail by expression?
A Cyclotron is a type of particle accelerator in which charged particles accelerate outwards from the centre along a spiral path. These particles are held to a spiral trajectory by a static magnetic field and accelerated by a rapidly varying electric field. The frequency is given by : ν=2πmqB.
What is the frequency of a cyclotron?
where ω is the wave frequency, Ω s = q s B 0 / m s is the cyclotron frequency for species s, k | | and v | | are the wave number and the particle velocity parallel to the ambient magnetic field, and γ = ( 1 − υ | | 2 − υ ⊥ 2) − 1 / 2 is the relativistic Lorentz factor.

What is the energy of a proton in a cyclotron?
If the particle is a proton, for example, then q = 1.60 × 10 −19 C, and its energy upon emerging from the cyclotron is 28 MeV. This energy is equivalent to that acquired by a proton accelerated through a potential difference of 28 MV.
What is the frequency of oscillations in a magnetic field?
The frequency of the oscillations is the same as the cyclotron frequency. The dees are placed in a uniform magnetic field directed perpendicular to the plane of the dees, and a source of charged particles is placed near the center of the dees. The charged particles are then accelerated across the gap between the dees.
