New Delhi, India – U.S. Energy Secretary Rick Perry and India’s Atomic Energy Minister Dr. Sekhar Basu signed an agreement today to expand cooperation between the two countries on the world’s leading scientific and technology project. The Long Baseline Neutrino Facility (LBNF), an international underground neutrino experiment in dune, organized by the US Department of Energy Fermilab, brings scientists from around the world together to discover the role that the tiny particles known as neutrinos play in the universe.
ASTEC’s work has put Britain at the forefront of neutrino factory research. The Neutrino Factory is a complex particle accelerator developed for the study of particle physics to generate intense, fast-focusing neutrinos. More than 1,000 scientists from 170 institutions in 31 countries are working with the International Deep Underground Neurino Experiment (Dune) on the Long Baseline NeutRino Facility (LBNF) hosted by the US Department of Energy Fermilab and celebrated its groundbreaking birthday in July 2017. The LBNF uses Fermil’s powerful particle accelerator to send the world’s most intense beams of high-energy neutrons into a massive neutron detector to study their interactions with matter.
The accelerator facility described in Section 2 contains improvements resulting from a significant amount of work by the Accelerator Working Group. Other subsystems have undergone a gradual evolution, but there is no evidence that the design of the neutrino factory has reached a certain degree of maturity. The start of the International Design Study of Neutrino Factories (IDS-NF) was the result of the International Scoping Study for the Future of the Neurino Factory Super Beam Facility (ISS).
The reference design for the primary beam, the neutrino beam, is suitable for an output power of 700 kW in this respect. Another aspect of the construction is the corresponding beam power (23 MW). This flexibility can be used to reduce the background beam tail and change the beam spectrum, which will be a systematic study in the future.
The detector system in LBNE design consists of the Beamline Measurement System (BLM), the Neutrino Detection System and the Neutrino Detectors. In order to tackle the oscillation process of neutrinos in the factory, each detector is able to identify and measure the three charged lepton aromas produced by charge-current interactions, measure their charge and distinguish between incoming neutrino helicity. In addition to the remote detectors, the design also includes a detector that monitors the neutrino beam as it leaves the Fermilab site.
A neutrino beam in a neutrino factory produces decays into particles called muons. The factory requires intensive cooling of the transverse phase space of the muon beam. In order to produce neutrons in sufficient numbers, the phase space required by the beam is reduced by cooling as the muons are accelerated.
Natural free atmospheric neutrinos provide the best opportunity to study neutrino properties. There is a good chance especially thanks to the high values to determine the neutrino mass hierarchy and to test the amplification of MSW resonance effects on the Earth matter. Superbeams with higher intensity than classical neutron beams produce protons that hit the target, while neutrons produce secondary particles that decay in the tunnel and stream back to the target.
