How to scan the position of the quadrupole to measure the emittance
Posted: 20 Oct 2017, 08:15
Hi All,
I'm a new to the elegant and I want to simulate the quadrupole scan method to measure the emittance. I have found an example in the ElegantExamples, in that example, the scan parameters are strength of the quadrupoles. Now I want to scan the quadrupoles' position, which can also lead to the change of the transfer matrix. When I change the parameter to the position, the results showed as follows:
Vertical emittance couldn't be determined
Horizontal emittance couldn't be determined
Horizontal emittance couldn't be determined
Vertical emittance couldn't be determined
Vertical emittance couldn't be determined
Horizontal emittance couldn't be determined
Vertical emittance couldn't be determined
Horizontal emittance couldn't be determined
Vertical emittance couldn't be determined
Vertical emittance couldn't be determined
The attachment is my input file .Any one can help me to solve this question? Thank you !
