| 199000 | Create photon bomb |
This ``interaction" allows the user to generate multiple Cerenkov photons as a single ``particle" The user has complete control over the first photon generated in exactly the same way as the ``Start a Particle" interaction. For the second and subsequent photons generated for the event, the user can independently control each attribute to be the same as the first photon or drawn from the same distribution. For example, it is possible to pick the first photon to be uniformly random in a time interval and with isotropic direction and to have all other photons generated at the same time as the first, but all with different directions drawn from an isotropic distribution. This interaction can be used to simulate a laserball when used with the laserball direction distribution and gaussian time distribution.
