Thread: voltage in a synchrotron

could you explain how do they produce potential drop between the Dee's? is there a vacuum? is it an electrostatic field?

A synchotron is just a type of cyclotron where the frequency is varied. This article describes the operation of a cyclotron.

The article states that it uses a high frequency alternating voltage. Since it is alternating, I don't think it would be described as electrostatic.
The way that a high frequency alternating voltage would be generated would be by some type of electronic oscillator.

Thanks Harold, I thought electrostatic field is more complicated to manage. I wonder if I understood right, but it seems that at every passage the particle gets same amount of KE, the equivalent of voltage drop. if it is so, isn't it strange?
