THE LHC RESTART AND NEW PROSPECTS

Interview with Roberto Tenchini, president of the INFN National Scientific Committee 1, which coordinates the institute’s activities in the particle physics sector, and researcher with the INFN Pisa Division


Last 22 April, the whole international particle physics community welcomed with interest and enthusiasm the news coming from CERN where two proton beams, each with an energy of 450 billion electronvolts (450 GeV), were injected in opposite directions inside the 27-kilometre underground ring of the Large Hadron Collider (LHC), the biggest and most powerful particle accelerator ever created. The restart of the LHC, which comes after a stop of almost three years, during which the machine and the four big experiments installed at the beam collision points underwent maintenance and upgrade works, was, in fact, the first step towards fully restarting scientific activities of the third data acquisition period (Run 3). ...


On 22 April, LHC was restarted with the injection of the first two proton beams. What does this initial switching-on stage of the LHC entail and how long will it last?

The LHC is a complex machine, a particle collider with a 27 km ring with a large number of components. Just to give an example: only the magnetic dipoles, which “bend” the beams, are 1232. The LHC itself receives the beams from the CERN accelerator complex. After a period of three years in which improvements were made and repairs carried out, we need to verify that each of its parts operates perfectly, increasing, step by step, the intensity of the packets of protons, the number of packets themselves, and their energy.

STANDWITHUKRAINE

THE CALL FOR UKRAINIAN RESEARCHERS AND TECHNOLOGISTS IS NOW OPEN

A first INFN call for applications (available on the Job Opportunities page on the website www.infn.it/en/) for research grants to support Ukrainian scientists is open. This call offers to researchers and technologists the possibility to work at one of the INFN facilities. "The objective of the positions offered by our Institute - explains Antonio Zoccoli, president of INFN - is to give concrete help to Ukrainian colleagues whose personal and professional lives have been devastated by this atrocious war. If this call is successful, the number of positions offered could be increased in the future."

INTERNATIONAL COLLABORATIONS

THE CONCLUDING STAGE OF THE PIP-II PROJECT APPROVED

The final phase of the Proton Improvement Plan-II (PIP-II), the upgrade of the Fermilab accelerator complex, kicks off. Fermilab is the main US centre for particle physics, in Batavia, Illinois. The Department of Energy (DOE) of the United States has, in fact, formally approved the start of works envisaged by the PIP-II, including a new superconducting linear accelerator of 215 metres (LINAC) that will produce the high-energy neutrino beam for DUNE (the Deep Underground Neutrino Experiment), in which INFN is also taking part.

MAGIC TELESCOPES OBSERVE A RARE GAMMA EVENT IN THE SKY

A new study conducted by the European collaboration MAGIC, published on 14 April in the journal Nature Astronomy, revealed the observation of a flow of high-energy gamma rays coming from a recurrent nova in the Milky Way. The event, the first of its kind to be detected at similar energies, sheds light on a class of astrophysical phenomena considered responsible for the periodic explosions that take place on the surface of novae - stellar bodies belonging to the family of white dwarves - and for the emission of a part of the photons that constitute the gamma radiation background that permeates our whole galaxy.

QUBIC: A NEW WAY OF STUDYING THE PRIMORDIAL UNIVERSE

On 21 April, eight articles were published in a special edition of the Journal of Cosmology and Astroparticle Physics authored by the international collaboration QUBIC (Q&U Bolometric Interferometer for Cosmology). QUBIC is creating a telescope in Argentina for studying the newborn universe that will make use of an innovative technique. QUBIC, in fact, will observe and map the properties of the cosmic microwave background, the residual echo of the Big Bang, concentrating on measuring particular components of the orientation of fluctuations in cosmic microwave...
