orbit ocrrection
Posted: 04 Oct 2023, 08:51
Dear Michael,
I am trying to correct the orbit in the x and y directions. I studied the related topics in the forum and wrote an ele file to correct the orbit.
My aim is to find the DA in the presence of misalignments and errors.
I used two types of commands:
1. &error_element name=*, element_type=*QUAD*, item=DX, amplitude=5e-6, cutoff=1 &end
(as the attached file with the name of 1)
for this command, I got a DA but ele cannot correct orbit in X and Y directions.
2. when I error command for each magnet separately as follows:
for example:&error_element name="Q1", item="dx", amplitude=5e-5, type = "gaussian", cutoff=1.0, bind=0, fractional=0 &end
(as the attached file with the name of 2)
ele cannot correct orbit in X and Y directions and no data set can be found to plot DA!
So, could you give me a comment to solve my problem, please?
I attached ele files and the lattice and errors that I faced.
Thank you in advance,
best regards
