consider the following script: ``` //--------------------------------------------- //----Element definition----------------------- //--------------------------------------------- foil: collimator, apertype=circle, aperture={0.000005}, aper_vx:={-a,-a,k,k}, aper_vy:={-a,a,a,-a}; a = 1.0; k = 0.1; //--------------------------------------------- //----/Element definition---------------------- //--------------------------------------------- beam; testseq: sequence, l=4; foil,...
The present OCTAGON is defined through 2 coordinates and 2 angles. The angles are normally computed by the user and not directly available in technical drawings. It could be interesting...
I'm getting test suite failures on test-cororbit-4 and test-match-10. Both appear to be roundoff, but I'd be a bit surprised about differences this large across Linux systems. 5.08.01, built from...
Hello, Currently, when performing tracking with `TRACK` and setting additional observation points with `OBSERVE`, one has the following options: - Setting `onetable` to `false` (default), one gets a file per...
In presence of crab cavities it is useful to calculate quantities similar to dispersions, but related to T-dependence. I propose to call them CX, CPX, CY, CPY. They can be...
It's not perfectly clear from user's guide how to include space-charge calculations in tracking. On page 200 in section 29.9 "Space charge" "several options" are mentioned. As I understood, OPTION,...
I am looking for codes computing electron beam polarization in alternative to the one I am using currently. Time ago Piotr Skowronski told me that it should be possible to...
From this example: ``` ss: sequence, l=3; mm: sbend, l=3, at=1.5,angle=0.01; endsequence; beam, particle=proton,energy=1.16; value,beam->beta; use,sequence=ss; twiss,betx=1,bety=1; ptc_create_universe; ptc_create_layout,model=2,method=6,nst=10,exact, time=false; ptc_twiss, no=2, icase=56, betx=1,bety=1, betz=1,closed_orbit=false; ptc_end; ptc_create_universe; ptc_create_layout,model=2,method=6,nst=10,exact, time=true; ptc_twiss,...

`JACOBIAN, STRATEGY=2` print the response matrix (jacobian) of matching problem and write a report based on the SVD. This works with USE_MACRO and it used to work in normal matching...
