Dear Michael, Thanks for your reply. As you meant, the beam in a quadrupole focuses in one direction and defocuses in the other. This phenomenon arises from the forces acting on the beam, which are directed into or out of the magnet center, while the field gradient maintains the same sign in both th...

Dear Michael, I have a periodic quadrupole magnet and I am tracking the 400 MeV electron beam through the 3D magnetic field map using Astra, BMAD, and ELEGANT. - In ELEGANT, BMXYZ and Ftable commands provide consistent results, but the intermediate Twiss parameters within the magnet are missed. As I...
