480 MeV proton on tungsten II
This is a story of a proton out for some fun, producing exotic particles through exotic collisions. The story was told to beautiful people by the beautiful beach of Maresias (Brazil) on 18th September 2014 at the 4th International Nuclear Chemistry Congress; the slides are here. This history has been cherry-picked (for less-probable events) from a simulation of 480 MeV protons impinging a 12 cm-deep tungsten target of dimensions 8 cm × 5 cm in beam’s eye view. The application is for the spallation neutrons to enter the warm moderator and cold moderator, eventually slowed down to ultra cold energies, stored in a bottled before being released to experimentalists as a unique probe into matter and creation. Particles attempting to escape are hurdled through shielding blocks of steel, concrete and hematite aggregates, to protect personnel, instruments and electronics downstream.
