Dear Dr. Didier, I am trying to do phase error in a 20 MeV DTL with 4 tanks. I have given command ERROR_DYN_FILE E:/SR/LEHIPA_DTL/dyn_error_file.txt before my DTL structure and included dyn_error_file000001 in the same directory. When I run the simulations, it shows error calculation but it generate...

Dear Dr. Didier,

I am using SET_SYNCH_PHASE before my RF field map line. The phase on the field map line is set at which location? Is it the center of the Field Map length?

Best regards,

Shweta.

Dear Didier,

Thanks for the clarification! This means the gap tilts in DTL is also accounted when we give coupled quad error.

Shweta.

Dear Didier, I understand that when we give quad error, TraceWin actually applies the error in beam reference point and then reverses the error at the output of the quad. In case of coupled quad errors, is it done in the same way, i.e., reversing initial error after individual quad or the error is a...

Dear Didier,

Thanks for the explanation. As regards the coupled quad error the tilted RF gaps isn't accounted. So, the error results may give an underestimate of the solution?

Best Regards,

Shweta.

Also, why beam tilt is not appropriate?

ERROR_QUAD command will not account for rf gap tilt, will it?

Dear Didier,

In order to simulate dtl tank tilt error, is it possible to use input beam error with dx, dx' , dy, dy' errors?

Dear Didier, I am trying to use steerer along with quad static error. The x and y steerer are set to same value in partran calculation, while in envelope they have different values. Beam loss ultimately increases with this correction applied. Kindly explain how to use steerer with Quad error. ADJUST...

Dear Didier,

Thanks a lot! That completely clarifies it.

Best Regards,
