Dear Didier,
Thank you very much for the information. Now, I can obtain the same results for both cases.
Best regards,
Bruce

Re: Longitudinal phase advance
Dear Didier, Thanks again for your explanation. Please allow me one more thing. Which is the matrix representation for an RF cavity for a field map in TraceWin? I found in the Manual the matrix for a bunched cavity. However, I could not find the matrix for an RF cavity for a field map in TraceWin. M...

Re: Longitudinal phase advance
Dear Didier,
Thanks for the information. In that case, Do you have any reference for that?
Finally a friendly comment. I think that the definition of K0s, it should include the division by period length. Or change Ko by sigma0.
Best regards,
Bruce

Re: Compensation failures proceed
Dear Didier, Thanks for your suggestion. As you recommended, I run a normal case to obtain the new lattice. Lattice.PNG In this case, you can see that the magnetic field of the solenoids for the left (normal matching case output) are the same as the ones in the new lattice (right). With the new case...

Re: Longitudinal phase advance
Dear Didier, Thank you very much, Yes, I should divide by the period length. About the phase definition, I am familiar with the expression of phase advance per period (sigma). It was that extra term " square root (1-determinant (Mxy))" that is new for me. Especially, because for Koz, the matrix shou...

Re: Compensation failures proceed
Dear Didier, I checked the performance of the "Twiss match with family and twiss command" for the transient simulations. I made two runs of the same lattice. On the left is the normal simulation and on the right with transient one. Test1.png Both have the same setting for matching with "Twiss match ...

Re: Compensation failures proceed
Dear Didier, About point 1). In addition to the "matching with family and twist command", I have a correction scheme using BPM and steering corrector. Thus, using your suggestion, I can not continue using the diagnostic correction. 2) Apologies, the failure time is correct. However,the settings of p...

Re: Longitudinal phase advance
Dear Didier, Thank you very much for the information. I computed Ko's according to that formula. As an example, I tested in the supra_1 example, given in the Example folder of TraceWin. Exe_1.png I used the values of the transfer matrix for element 7 (the last element in the period) to compute K0z. ...

Longitudinal phase advance
Hi, First, Could you explain how GenLinWin computes the phase advance per unit of meter? Is using an expression like Kz.PNG ? Second, About the equation for the phase acceptance, I think that the exponent is 3/4 instead of 4/3. According to the reference phase_acceptance.PNG Is that correct? Thanks ...
