Re: Unexpected change in particle momentum with skew quadrupole

Dear Michael,

Another thing. Could you please also add the 'ElementName' of the lost particles, in the loss file? Now only 's' is saved.

That would be convenient.

Best regards,
Björn

Unexpected change in particle momentum with skew quadrupole

Dear Michael, We are using Elegant for slow extraction simulations of SIS100 at FAIR. When introducing a skew quadrupole element to study coupling-induced resonant losses, we observe that vertically lost particles sometimes show a significantly modified total momentum, p, in the loss file, 1.43 inst...

Amplitude dependent tune shift

Dear Michael, I have a question regarding the calculation of the amplitude dependent tune shift parameters, dnux_dJx, dnux_dJy , dnuy_dJy which are displayed in the twiss output file. We are using these to evaluate the influence from different elements on the non-linear dynamics of the resonant extr...
