Currently the user can set the beginning element Twiss via a command like `set ele beginning beta_a = 1.2345`. However, it is often needed to set the Twiss in the middle of a lattice. Rather that rely…

_calc_twiss_ now takes 80 ms on my I7 computer. 60 ms are from _findm66_ using TPSA which gives transfer matrices from passmethods with computer accuracy. For VACA purpose, should a fast and dirty _ca…

Below is a tentative list of what elements should be defined in the Standard. This list is not exhaustive (this is just the beginning and I expect that there are more elements added). Also I am not su…

When activating the crab cavities, the calculation of the sigma matrix (SIG11 - SIG66) seems to be wrong,
e.g. beta_x * emittance_x != sig_11 , for small (i.e. LHC-like ex

Hi,
I just got the error using the tfs2pd function:
AttributeError: _TFS instance has no attribute 'S'
Indeed, I'm trying to read a twiss file produced without any details on the columns na…

Tapering does not restore tunes in PTC_TWISS and in TWISS.
I understand from manual (chapter 38) that TWISS calculates optic functions in 4d only, therefore it is expected that with RF cavities and…
