1. The LHC is the world's largest and highest-energy particle accelerator.

2. Caspar is a low-energy particle accelerator that allows researchers to study processes that take place inside collapsing stars

3. With a beam energy of 1.5 GeV, the first high-energy particle collider was ADONE, which began operations in 1968.

4. In particle detectors built at high-energy particle accelerators, a device called a calorimeter records the energy of particles by causing them to produce a shower and then measuring the energy deposited as a result.

5. The early history of the Bevatron is the well-documented in the attached HAER including the Bevatron’s early research work associated with four Nobel prize winners and their important contributions in the research areas of high-energy particle physics, heavy-ion nuclear physics, medical research and therapy, as well as space-related studies
