Twiss for varied momentum

Hi All, Can elegant calculate twiss parameters for varied momentum? I try the following: &twiss_output filename=%s_0.twi output_at_each_step=1 radiation_integrals=1 compute_driving_terms=1 concat_order = 2 &end &run_control n_indices = 1 n_steps=3 &end &vary_element name=MAL, item=DP, initial=-0.04,...

Amplitude of driving terms

Dear Michael and collaborators,

Is there a way to calculate and plot the driving terms as functions of position a long a ring?
I am trying to cancel the resonance terms accumulated in the ring.

Many thanks,
Thapakron

Re: MOGA optimizer for rings

Hi Michael The Area obtained from Elegant is correct (zero when there is no aperture). But during the clipped Area (Area1) calculation by the script "processJob", it gives some large constant value for example *** Area_check :0.000000000000000e+00 (from .aper) Area1_check:1.005000000000000e+00 (afte...

Re: MOGA optimizer for rings

Hi Michael I have tried to used MOGA optimizer to optimize beam emittace and DA. I found some problem with the DA calculation process in "processJob" script which integrate the clipped area. It give abnormal large area when the unclipped area is zero. mpl.png Those with the large area have DA like t...
