The brand new linear particle accelerator will feed the CERN accelerator complex with particle beams of higher energy, which will allow the LHC to reach higher luminosity by 2021. The peak luminosity of the LHC is planned to be increased by a factor of five by 2025. This will make it possible for the experiments to accumulate about 10 times more data over the period 2025 to 2035 than before.
CERN has inaugurated its shiny brand new particle accelerator which will continue researching the universe and other fields in the near future.
The latest upgrate—the Linac 4 machine—replaces the injector that’s around forty years old. Its mission is to produce the flow of particles for the Large Hadron Collider or LHC, the 27-kilometre accelerator that smashes protons together for science.
“We are delighted to celebrate this remarkable accomplishment. Linac 4 is a modern injector and the first key element of our ambitious upgrade programme, leading up to the High-Luminosity LHC. This high-luminosity phase will considerably increase the potential of the LHC experiments for discovering new physics and measuring the properties of the Higgs particle in more detail,” said CERN Director General Fabiola Gianotti.
“This is an achievement not only for CERN, but also for the partners from many countries who contributed to designing and building this new machine,” said CERN Director for Accelerators and Technology Frédérick Bordry. “Today, we also celebrate and thank the wide international collaboration that led this project, demonstrating once again what can be accomplished by bringing together the efforts of many nations.”
The construction of the accelerator, which is almost 90 meters long and located 12 meters underground, took approximately 10 years and cost close to 100 million dollars. It is part of a chain of five accelerators of different dimensions CERN works with and is estimated to triple the energy production in relation to its predecessor, Linac 2, with 39 years of operation.
As reported by Phys.org, this is the first step to increase the overall brightness of the LHC by five times until 2025, and thus get up to 10 times more data than scientists are getting today. In this way, the Linac 4 will allow more precise measurements of particles and will help the development of portable accelerators, with future applications in the field of medicine and industry.
According to a press release, Linac 4 will send negative hydrogen ions, consisting of a hydrogen atom with two electrons, to CERN’s Proton Synchrotron Booster (PSB), which further accelerates the negative ions and removes the electrons. Linac 4 will bring the beam up to 160 MeV energy, more than three times the energy of its predecessor. The increase in energy, together with the use of hydrogen ions, will enable double the beam intensity to be delivered to the LHC, thus contributing to an increase in the luminosity of the LHC.
The new machine took 10 years to build and cost 85 million euros.
As reported by Euronews, researchers at CERN are building a prototype design to be used by museums, enabling institutions to analyses and verify the authenticity, age, and composition of paintings.
