Hey mate...Principle of. cyclotron is as flws: Cyclotron is a device used to accelerate charged particles to high energies. It was devised by Lawrence. Cyclotron works on the principle that a charged particle moving normal to a magnetic field experiences magnetic lorentz force due to which the particle moves in a circular path.
I ain't thurrow wie derivation..but yah here's some explainationParticle velocity has been a major consideration and it has been shown quite clearly that there is a threshold value of particle velocity below which no degradation occurs. The value of this particle velocity for the aluminium oxide was about 10 m/s and was influenced only slightly by particle size, target material, and particle impact angle above about 15 degrees

At velocities only slightly lower than this, however, the mode of conveying changes from dilute phase suspension flow, to dense phase non-suspension flow, for many of those materials capable of being conveyed in dense phase. In dense phase conveying little impact occurs in horizontal pipelines and the mode of conveying mostly involves sliding of the particles through the pipeline. With materials having good permeability, conveying is in plugs and slugs, and for materials having good air retention, it is as a moving bed along the bottom of the pipeline.
