Dear Didier,

I appreciate the phase adjustment tip for working with the RFQ field map in TraceWin.
Your guidance is very valuable. I’ll take this into account in my simulations and adjust the RF phase accordingly.

Dear Didier,

i did further testing today. When i changed the beam current from 2mA to 5mA, this issue appeared again.
In addition, how to determine the RF phase of the RFQ field card? Why is it -50°? And could you plz provide me some references?

Best regards,

Dear Didier, Thank you for the explanation. i have proceed with a test using the latest version of TraceWin. The .dat file is as below: Drift 0.00001 6 Drift 0.00001 6 Field_map 00700 2552.400 -50 3.162 0.0 1.0 0.0 0 3IBCs2_phase57b 1 Drift 0.00001 6 Drift 0.00001 6 END The RF phase of the field car...

Dear Didier, Great! The difference of the transverse phase space is solved in the latest updated TraceWin. For the multi-bunch effect at the RFQ output, there still seems to be multiple bunches at the RFQ output when i adjusted the RF phase of the field card to -50° as you suggested. The original ph...

Dear Didier, Thank you for the update and the corrections you’ve made in TraceWin. I’ll proceed with some tests using the new settings, adjusting the RF phase of the field card to -50° as you suggested. I’ll analyze the results to see if it works out. Once I have more data, I’ll get back to you. Bes...

Hi Didier,

Thank you for your response. Please let me know if there is any additional data I can provide to assist you with your investigation. I look forward to hearing from you once you have had the opportunity to review the situation further.

Thank you again for your support.

Hi, I have built a RFQ electrode model and got the 3D ES field by CST EM Studio. But I have encourtered a problem when i run the same one input(same .ini, .dat, .edx, edy, edz...) on different sw versions(2.18.02 and 2.24.04). Below is from sw version 2.18.02 : 1.PNG And if merge the two longitudina...
