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...

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. ...

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 ...

Dear Didier, Thanks for your comments. 1) For your suggestion "For your first request, I could by default cancel intial ADJUST process at beggening of the run, when transient simulation is selected. What do you thing about this solution" In that case, Can I still apply the matching options "Match wi...

Dear Didier,

Sure, thanks for the help.

Dear Didier, Thank you for your help, I came again with a request. In the past, you suggested removing the matching options and matching diagnostic. This works fine in most cases; however, in another, I need to make a match to avoid emittance growth. The matching options were removed because at the ...

Dear Didier, Re-taking again the transient studies. I am trying to apply for compensation in a transient regime. The next figure shows the model that I am using (that we discussed in the past). Lattice.png There the second cavity has a faulty behavior, the details of the Cav file and the simulations...

Dear Didier, Thank you very much for the information. I have to more questions: 1) About the equation "Q0i=Qolow-(3./4.)*Qolow*Eaccnom/10e6;", Could you tell me how this equation is obtained? or some references. 2) When you said that "Qi is calculated one time in the beginning"? Do you mean that lat...

Dear Didier, On the manual, the quality factor of the loaded cavity (QL) is given by: 1/QL=1/Q0 + 1/Qi + 1/Qt... (1) How TraceWin estimated the incident coupling (Qi)? Qt is given, and Q0 can be estimated from the input parameters. I would like it if you could explain to me a little more about Qi. B...

Dear Didier,

I see. Thank you very much for your explanation.
