Re: How to calculate emittance

However, even when the button click is replaced with the calculated maximum value of X based on the rms size, it still does not match the result obtained from this formula. Could it be that some additional factors have been included in the calculation?

How to calculate emittance

Dear author
I would like to know what formula was used to calculate the value of Xmax in the circled part of this picture. If the reference is made to the circled part in the second figure, this calculation result is incorrect.

Re: How to define dispersion in the input of tracewin

Dear author : I intended to use the tracewin software to reproduce the results of the old beam dynamics software transport, but the two results were completely mismatched, especially the twiss parameters at the bend were completely incorrect. Since the initial definition of the transport software fi...

How to define dispersion in the input of tracewin

Can the horizontal dispersion and the derivative of dispersion be defined by adding corresponding values to the thin_matrix, such as defining values at T15 and T25?

the adjustment of dipole/bend magnet

Is there a way to adjust the parameters of a dipole/bend magnet to match the twiss parameter value I want (without changing the length of my dipole/bend magnet)?

the loss of particles

Why is there a loss of particles when only the length of a drift segment is missing in the middle? Moreover, it can't be seen from the figure that the main particle beam cluster is lost, and the radius of my drift segment is large enough. Why is there still a small amount of particle loss?

Re: The main difference of data identification in X direction and Y direction in the field map.

Dear author, I have a question, which is what algorithm is used to generate the data behind a multipole field map? Or what is the algorithm of the field map generated by the data? Thank you. I really don't understand the instructions. regards, hanxj
