Dear fluka experts,




Excuse me, I have a question to ask for your help. The description is as follows:




After the beam in the Undulator of a high-energy electron accelerator hits the profile target,

part of the high-energy electrons generate electromagnetic shower with the vacuum chamber wall,

and a large number of secondary electrons are generated outside the wall.

There is an optical fiber next to the outside of the vacuum chamber.




I want to obtain the number of these secondary electrons passing through the optical fiber,

the incident angle information (relative to the beam direction), the relativistic velocity and the path length in the optical fiber.

Thank you very much for any suggestions you can provide!




In addition, if you can, thank you very much for providing relevant examples about Cerenkov radiation generating and propagating.




best regards!
