Dear Didier, Does that mean when I give coupled quad error, all quads are rotated about an axis passing through the center of the tank and not the center of individual quad? I was assuming that the center of the first quad falls on beam axis, and rest all are rotated by the given tilt. But now it ap...

Dear Didier, Can you please elaborate how do you get this displacement error values because as much as I understand the first quadrupole should have pure rotation error. Second and subsequent quads may have displacement error. Also a rotation about x axis will create displacement in y direction. But...

Another doubt is that when i give quad tilt about x in DTL, the error data file does contain the tilt but also shows non zero x displacement error. Why is it so?

Dear Didier, Thanks for your response! However, as much as I understand DTL_CEL line is not affected by cavity misalignment errors. They are affected by field errors only. Please correct me if I am wrong. I have already given coupled quad error, but am not able to tilt the RF gaps as per my requirem...

Dear Dr. Didier, I need to simulate DTL tank tilt along one transverse direction which is our practical scenario. There is a tilt in tank in the transverse direction perpendicular to stems of about 0.023 deg. In TraceWin, such an error doesn't exist. Could you please suggest how to go about carrying...
