All particle lost, but give DA area very large

[lyyang]

Hi,

I got a large DA, with a set of sextupole, but found that during the tracking of "find_aperture" all particles are lost.
Then the (x,y)=(+/-1, +/-1) are the default one ? the Area=2 m^2. are they supposed to be zero ?

Thanks

Here are the ouput:

I think this is a bug. I never prepared the algorithm to deal with all particles being lost.

If you can post the input files (or email them to me), it would make it easier for me to understand what's happening.

Hi Michael,

Thanks for looking at this problem.

Here are the lattice file and kickmap.

Lingyun,

It is indeed a bug. The attached file contains the fix, which you can use if you build from source.

Otherwise, a workaround is to postprocess the file, which can be done by adding this command at the end of the input file
&subprocess command = "
sddsprocess %s.aper -redefine=parameter,Area,\"Area 2 == ? 0 : Area $ \"
" &end

Michael,

Thanks for this quick fix, I didn't build from source code, so the post process would be a best solution for me now.
