Producing EB Waves: Accelerating and Decelerating Particles

Click For Summary
SUMMARY

Charged particles produce electromagnetic (EB) waves when they accelerate or decelerate due to external forces. The energy radiated in the form of EB waves originates from the particle's kinetic energy or work done by the external agent. In circular electron accelerators, such as synchrotrons, this radiated energy contributes to increased electric power costs. Understanding the relationship between particle motion and EB wave production is crucial for optimizing accelerator efficiency.

How does a charged particle, that is accelerating or de-accelerating, produce an EB wave? What is actualy happening when an EB wave is produced? The EB wave has energy, what is happening to the energy of the charged particle? Is the charged particle slowing down, if so why is an EB wave produced for a de-accelerating particle as well?

Charged particles don't accelerate or decelerate by themselves. They do so in response to some external force. So the energy that is radiated away can come either from some of the particle's kinetic energy, or from work done by the external agent, or both.

In a circular electron accelerator (synchrotron) or storage ring, the radiated energy shows up in the accelerator's electric power bill.
