Hi! I'm new to Geant4, so maybe my questions are a little stupid.
I have been trying to simulate neutron transportation using Geant4, and my model consists of several tubes,whose centers are located in the same point. My neutron source is one of those tubes. In order to get the relationship between the neutron flux and the radius of different side surfaces of those tubes, I want to have all upper and lower surfaces of the tubes set as reflecting surfaces(i.e.,a particle track that hits a reflecting surface is reflected specularly.), but I haven't figured out how to achieve this. Can anyone help me fix this?
My model is shown in the attachment.
Thank you sincerely. Jincai.
