Dear Didier, I understand that introducing independent relative errors on Ex, Ey, and Ez may be difficult. A simpler possibility could be to introduce a random angle theta that modifies the transverse field components as follows: Ex' = Ex cos(theta) - Ey sin(theta) Ey' = Ex sin(theta) + Ey cos(theta...

Dear Didier, In TraceWin, it is possible to include errors in the cavity-field, from a field map, amplitude (E), expressed as a percentage. However, in superconducting cavities, effects such as thermal deformation may also modify the relative contributions of the electric-field components (E_x;E_y;E...

Dear Didier,
yes! now GenLinWin accept the FDF period.

Dear Didier, I've done a linac design by using GenLinWin. What I've noted is that is reported by the envelopes plots a not correct sequence of elements, i.e. in the attached envelope.png the yellow box should be reported only two times, because I'm using two cavities. Instead the FM1 and FM2 maps ar...

Dear Didier,
in our linac at LNL we have a period formed by a triplet and a cryostat.
May you you insert in the Period type list also this combination:
F-D-F-Cryostat.

Dear Didier, I'm doing some calculations about the ESS DTL. I've observed that the DTL_CEL line is somehow different respect to the GAP line, i.e.: DTL line on TraceWin: DTL_CEL 75.23682 25.0 24.6445 0.00999151 -59.9444 0.0 176192.0 -35.0 10.0 3.0 0.0884558 0.780607 -0.378458 -0.163516 ; Relative ph...

Dear Didier,
Apologies for the oversight. We've reviewed the files, and you are absolutely right — with the latest version, the code works correctly, just as it did before.
Thank you for pointing that out.
Best regards,

Dear Didier,
I've still problems to center the dipole map.
I've simplify as much as possible the project and I put it here.
The dipole fileds map is the same as before (working from 2016 to 2021).

Dear Didier, I've seen that the project .dat file in the calculation directory report the values coming from the envelope matching also when has been used the partran macthing. Is this a correct behaviour of the Tracewin program ? In the attached example, I was aspetting 8323.34 V in the test_t1.dat...

Dear Didier, we try to simulate a tracewin line from 2021, which contains two dipole fieldmaps which perfectly worked in the past Tracewin version. However we noticed that, with the new versions, we had some losses inside the dipoles, apparently because all positive energy particles are canceled fro...
