Re: Synchrotron motion in a damping ring

Hi Michael, I found that during tracking: 1. Without RF and turn off the radiation damping, I get this (see picture) 2. without RF, turn on the radiation damping, I get this (see picture) Both results give a deltaT shift in longitudinal phase space. I thought this deltaT shift is unreasonable becaus...

Re: Synchrotron motion in a damping ring

Hi Michael, Thanks for your explanation. But the value of energy loss seems not the answer. Actually, I’ve tried to turn-off the radiation damping in the lattice and I confirmed that the momentum value keeps a constant during tracking (without RF). But when I added the RFCA element (phase=180) with ...

Synchrotron motion in a damping ring

Dear all, I have a damping ring with a series of wigglers (cwiggler) in the lattice. I was trying to simulate the synchrotron motion, but I found the result seems not correct. As shown below, the dp/p reachs to 0.15, which is huge. In the tracking, the particle (only one) was on-mementum and I used ...
