Michael,
There is rather annoying bug in QUAD element with HKICK or VKICK steering used. If you divide the quadrupole using "divide_elements" command then the steering kick value is simply copied to each slice. This results in many-fold increase in overall steering.

Thanks.
Alexey.

Alexey,

Sorry about the bug. It will be fixed in the next release. Meanwhile, if you want a workaround, try

&divide_elements name=*, type=QUAD, divisions=10 &end

&run_setup .. &end

&alter_elements name=*, type=QUAD, item=HKICK, value=0.1, multiplicative=1 &end
&alter_elements name=*, type=QUAD, item=VKICK, value=0.1, multiplicative=1 &end

If you build from source, you can try substituting the attached file for track_data.c

Thank you, Michael. I really appreciate your help!

This was fixed in release 23.1.0
