Access to tracking_based_matrices

Post by Nagaoka » 23 Oct 2023, 06:23

Hello,

I would like to know if there is a way to write out and have access to tracking_based_matrices obtained such as on a BGGEXP element.

Thanking you in advance for your kind instruction,
Ryutaro Nagaoka

Ryutaro,

You can get the matrices from the matrix_output command. It provides the option for a text file or an SDDS file.

Hello Michael,

I thank you very much for your helpful instruction. I just tried using this option and I do get matrices for each element in the beamline as well as concatenated matrices. I suppose that the matrices for the BGGEXP elements are obtained from many particles tracking.

The convention for the matrix elements C1, ..., C6 and Rij (i,j=1,...,6), as well as the coordinate system that goes together with the former, can it be found somewhere?

Thanking you again Michael for your kind help,
Ryutaro
