is for accelerator,
which makes things move fast.
Accelerators take tiny particles and speed them up. They can smash particles into a piece of matter or make two particles collide head on. They are in operation around the world, serving medicine, industry, energy, the environment, national security, and discovery science. In particle physics research, scientists use accelerators to discover new particles and explore how the universe works.
is for black holes:
they have lots of mass.
Black holes are extremely dense, with so much gravity that even light cannot escape them. Within a black hole, the known laws of physics go out the window. Scientists think there could be around 100 million black holes within the Milky Way galaxy and estimate billions upon billions more in the universe.
is for cryostat,
so icy and cold!
A cryostat is an apparatus that keeps things very cold. Many pieces of particle physics experiments work only when they’re chilled to very low temperatures, as little as a few degrees above absolute zero. Cryostats keep superconducting materials cold enough to conduct electricity without resistance, and they can keep particle detectors cold enough to register even the most miniscule deposits of energy from particles such as dark matter.
is for detector,
where collisions unfold.
Particle detectors are scientists’ windows to the subatomic world. When a particle hits a detector, it gives up information such as its energy, direction, speed and electric charge. Detectors are often made up of multiple layers and devices to measure these different aspects of the particles they study and to figure out the identity of the particles they detect.
