I am questioning what the higher order terms consist of when asking for higher order terms in a quadrupole. E.g. by setting: quad, order=4. I would expect the expansion to be only in energy, while the quad remained perfectly linear in the transverse. However, using the following test case, this seem...

Dear Michael,

Thank you for the quick reply. Yes, it would be awesome and I believe useful for a number of people to have a lens element. An upright quadrupole with the option to set the same focusing for x and y would do the job as a simple lens.

Best regards, Erik

Dear all, We are trying to integrate a simple plasma lens effect into our elegant simulation. The model we want to implement is quadrupole focusing, in both planes simultaneously. Our beams may have energy spread of order delta = +/- 50%, so the energy dependence of the focusing must be taken into a...
