meaning of element (RFDF) parameters

Post by gpark » 08 Dec 2017, 09:23

I want to know the meaning of the parameters, START_PASS and END_PASS, of the element RFDF. I read the manual, but I couldn't figure out their meaning. Could you explain the description in more detail?

Thanks
Gunn

Gunn,

These parameters are intended for use in ring simulations, where the beam goes around many turns ("passes" in elegant's lingo). They allow gating the cavity on and off. So if you want to have the cavity turned on only for passes 10 through 20, you'd use

Code: Select all

START_PASS=10,END_PASS=20
