Cyclotron Basics for a Proton
The kinetic energy K of a proton in a cyclotron is given by:
K=(q^2 * B^2 * R^2)/(2m)
where:
- q = charge of the proton (1.602×10−19 coulombs), electron is negative that
- B = magnetic field strength (teslas, 10 is a lot, 20 is a lot lot)
- r = radius of the cyclotron (meters)
- m = rest mass of the proton (1.673×10−27 kilograms), electron is 9.109×10−31
Lorentz
- K = (gamma - 1)(mc^2)
- gamma = 1 + K/(m * c^2)
- v=c*sqrt(1-((1/gamma)^2))
- gamma = 1 / (sqrt(1-((v/c)^2)))
- sqrt(1-((v/c)^2)) = 1/gamma
- 1-((v/c)^2) = (1/gamma)^2
- (v/c)^2 = 1-((1/gamma)^2)
- v/c = sqrt(1-((1/gamma)^2))
- v = c * sqrt(1-((1/gamma)^2))
