1. The problem statement, all variables and given/known data Calculate the head to tail bunch differential acceleration from beam loading on an RF cavity. 2. Relevant equations Frequency 201 MHz Stored energy varies as E^2 Acceleration varies as E Use any other variables that might be needed 3. The attempt at a solution Don't really know where to start. I've done my best to understand the concept. I know that once the beam enters the cavity, it becomes pulsed at the same frequency as the RF. I just need someone to concisely explain what I'm supposed to be calculating so I can do the rest of the work myself.
