There are a major errors on this entry. Those are the problems solved by the synchrotron not cyclotron!
1-29-2012 Wasen't the 1st cyclotron built by Livingston based on designs and data from Lawrence? I thought he took the failed Lawrence/Edlefsen system and retooled in into a working system in 1931 — Preceding unsigned comment added by 67.163.253.56 (talk) 03:53, 30 January 2012 (UTC)

I don't find it surprising that a description is less well known than the working example. Other features of particle accelerators, and almost everything else were theorized or speculated about long before they were put into practice. David R. Ingham 02:12, 24 April 2006 (UTC)
On http://en.wikipedia.org/wiki/Image:Cyclotron_with_glowing_beam.jpg it is said the glow is not because of Cherenkov radiation, who is right ?
surely the point of the cooling pipes is to remove heat (power) caused by resistive and dielectric heating of the electrodes by the AC field , not the trivial heat produced from a miniscule number of particles escaping the confinement?

I came to read it and the entire page was filled with badly spelt warnings from a hacker, demanding money from the government etc. I checked this discussion page and it was ok. After looking up 'revert' in wiki help, the page reverted itself to genuine content. Please check history to confirm. --TresRoque 17:13, 30 January 2007 (UTC)
I suggest to include in the "mathematics" section that units are SI. The expression are different in CGS. BTW, it could be include both of them. —Preceding unsigned comment added by 150.163.28.83 (talk) 12:25, 6 December 2007 (UTC)
I went to the front section and made some edits for accuracy. There seems to be some people who insist on curved geometry in high-energy physics, but the cyclotron as a working machine demonstrates a spiral particle path caused by the angular displacement of the particles. The degree of angular displacement is a function of the speed of rotation (a function of the frequency of the power supply), and the centrifugal force driving the accelerated particles out towards the rim of the containment.
The resulting geometry is fractal, not curved. The particle acceleration path forms a spiral of definable length. This is a key acceleration path in nature, as can be easily verified by examining spiral galaxies in a telescope, or watching water go down a drain. This is the same acceleration path used in magnetrons and other high energy, non-linear, accelerators & resonators.
More and more theorists are coming to grips with a fractal string universe with coiled, not curved geometry as the base function. The cyclotron is an example of this geometry in a working machine
Cyclotrons can produce circles though can't they? We did the typical cyclotron experiment showed in the picture here in school and we made a circle when the surrounding magnetic field was strong enough. Frederickhoyles (talk) 21:02, 14 January 2009 (UTC)
With no change in energy the charged particles in a magnetic field will follow a circular path. In the cyclotron, energy is applied to the particles as they cross the gap between the dees and so they are accelerated (at the typical sub-relativistic speeds used) and will increase in mass as they approach the speed of light. Either of these effects (increased velocity or increased mass) will increase the radius of the circle and so the path will be a spiral.
(The particles move in a spiral, because a current of electrons or ions, flowing perpendicular to a magnetic field, experiences a perpendicular force. The charged particles move freely in a vacuum, so the particles follow a spiral path.) The radius will increase until the particles hit a target at the perimeter of the vacuum chamber.
Aren't the above two paragraphs contradictory? Overmage (talk) 08:28, 3 March 2010 (UTC)
