Muon propagation through several media Q: Is it possible to propagate muons through more than one media with MMC?
There are two ways of propagating muons through more than one media with MMC. For the rock and ice configuration in AMANDA, with ice above z=-1080 m and rock below, the setup could be either one of the following two choices: • For flat geometry run ammc -r -surf=-1080 -face -medi=”Standard Rock” [other options] | ammc -r [other options] This propagates muons to and through the detector whether the they originate from inside the rock or ice (thanks to “-face” option, which leaves all muons propagating from above the plane z=[h] unchanged). The coordinates of the muons moving toward the plane z=[h] at the end of the pipe will be given at their intersection point with the plane z=[h], since the fisrt program moves the muons to the plane and updates their coordinates, and then the second acts as usual: it only updates the muon track length and creates secondaries in the active volume of the detector. • Create a media definition file with contents as follows: # media definition file # inclu
