Electron-ion collider project could reveal atomic nuclei mysteries

The video tutorial explains the process of using beams of electrons and protons, or ions, accelerated to near-light speeds to collide at intersecting points. These collisions, surrounded by detectors, generate virtual photons that help analyze the internal structure of protons or nuclei, revealing the distribution of quarks and gluons. Two facilities, Brookhaven National Laboratory and Jefferson Lab, have submitted proposals to host the Electron-Ion Collider (EIC), each with different existing capabilities and requirements.

What is the purpose of colliding beams of electrons and protons at high speeds?

• To create new elements

• To study the resulting interactions

• To generate electricity

• To produce sound waves

What do virtual photons do when generated from collisions?

• They change color

• They penetrate the proton or nucleus

• They disappear immediately

• They create new particles

Which particles' distribution is revealed by virtual photons?

• Electrons and positrons

• Neutrons and neutrinos

• Atoms and molecules

• Quarks and gluons

What does Brookhaven National Laboratory currently lack for hosting the EIC?

• A neutron detector

• An electron ring

• A proton accelerator

• A photon generator

What additional component does Jefferson Lab need to host the EIC?

• A neutron source

• An electron accelerator

• A photon detector

• A proton ring
