Thank you a lot for your helpful comment.
I used daopt in PAR and optimized the DA in the bare lattice and the lattice with octupoles.
Best regards

Dear Dr. Borland, I have one question. I employed octupoles in the lattice of ILSF and optimized it to find the DA. Then, I considered the errors in finding the DA in a real lattice. I found this: Picture1.png I try something to increase the DA in the presence of errors. For example, reducing errors...

Hello Michael,
I did it and my problem is solved. I really appreciate your help.
Thank you.

Hello Michael and all, I calculated the tune shift with amplitude by tracking and using SDDSNAFF. I found the following graphs for the horizontal and vertical directions. Tune y.png Tunex.png Now the problem is that the value of the fractional tune at the (x0=0, y0=0) is (0.32, 0.16) which does not ...

Thank you for your useful comments. As you mentioned, I used the tune footprint script to find the tune vs. amplitude. There are two points: 1. I do not see why the trend of the plot of the tune footprint script is not reasonable! 2. I used another script in which I tracked particles and then found ...

Dear Michael,
Thank you for your comment.
I have a 40401*4 grid, including x,y, Bx, and By.
I choose 25 or even 50 rows of data and make another grid to do field mapping with bmapxy.
I hope the grid works this time.

Dear Michael, I am trying to plot amplitude-dependent tune shift using TwissCalculation. I calculated amplitude-dependent tune shift manually by using the tracking script. I found the tune in different y and constant x and vice versa, but the points are limited. I am going to find ADTS in x=-20mm to...

Dear Michael, During working with BMAPXY, I was not able to map the quadrupole field using this function. As a result, I made changes in my ling CSV file (as attached "small1 or 2"). Unfortunately, I cannot do field mapping yet. In small1.csv, there are 4 columns (X, Y, Bx, By), and in small2.csv, t...

Dear Michael,
Thank you for your help.
Best Regards

Dear Michael,
Thank you for your comment.
So it is needed to correct the csv file. I'll try it.
Thank you once again.
