Members of the Simons Foundation and the Heising-Simons Foundation visiting ATLAS and FASER

The funding of FASER (ForwArd Search ExpeRiment) from the Heising-Simons Foundation and the Simons Foundation made it largely possible for FASER to perform its experiments on the LHC. The FASER detector sits in the underground LHC tunnel about 500 meters away from the ATLAS detector. It takes data from the collisions which happen as proton beams pass to collide inside the ATLAS detector. These collisions may create new particles that will go through concrete in the LHC tunnel and thus into the FASER instrument, which will track and measure the progress of their decay. FASER will collect data any time ATLAS is operating. FASER is part of one of the smaller experiments on the LHC.
