Diagram of a linear proton resonance accelerator, or linac, showing protons entering from a source, passing through a series of labeled drift tubes powered by a radio-frequency source, and exiting as a beam through a cavity. — particle accelerator The accelerator is a large-diameter tube within which an electric field oscillates at a high radio frequency. Within the accelerator tube are smaller diameter metallic drift tubes, which are carefully sized and spaced to shield the protons from decelerating oscillations of the electric field. In the spaces between the drift tubes, the electric field is oriented properly to accelerate the protons in their direction of travel.

CERN’s mission to foster international collaboration in particle physics necessitated the rapid transmission and communication of experimental data among scientists globally. To address these research needs, CERN required a more efficient way for researchers to share results, techniques, and practices without the constant exchange of emails.12

In 1989, computer scientist Tim Berners-Lee proposed a global hypertext system to solve this challenge. By allowing researchers to place information online for immediate retrieval by peers, the system facilitated seamless collaboration. Berners-Lee developed the necessary software for the first Web server and Web client between 1990 and 1991. Introduced to CERN in 1990, this system became the World Wide Web, transforming communication not only for the high-energy physics community but for the entire world.12
