A 1-sq-m fast plastic scintillation detector is used to detect the arrival time distribution of extensive air showers. It is placed under 1 m of concrete and 3 cm of lead. The detector has a rise time of 3.4 ns (2000 V), and its diametser is 127 mm. The system (detector, oscilloscope, and camera) has a response to a single particle corresponding to a rise time (10 percent to 90 percent) of 4 ns and a full width at half maximum of 6 ns. Several background processes are considered and shown to be negligible. Above 10 to the 17th eV, the nuclear interaction changes and new stable particles with heavy masses may be produced. Near the top of the atmosphere, cosmic-ray particles with energies around 10 to the 17th eV interact with air nuclei and produce new particles. These also interact with air nuclei to produce many secondary particles. It is believed that as the energy of a new particle decreases, it produces secondary delayed particles. The mass of the new particle will be greater than approximately 1 TeV/c-squared. It is pointed out that the particle may be more fundamental than a quark.
