Neutrino Physics & Experiment

1. Past History

Neutrino physics has had an interesting history. In 1930 Dr. Pauli postulated the existence of the (electron) neutrino, in 1956 this was confirmed by Drs. Reines and Cowan using a nuclear reactor source of antineutrinos. In 1962, a second distinct (muon) neutrino was shown to exist in a BNL experiment. For that discovery Nobel Prize was awarded to Drs. Lederman, Schwartz and Steinberger. In 1995, the third, (tau) neutrino was detected at FNAL. In parallel, Dr. Ray Davis' studies of solar neutrinos confirmed understanding of stellar dynamics modulo a 2/3 flux deficit that later was recognized as a result of ν oscillations among the three flavors of neutrinos. Properties of those oscillations were further unveiled with followup solar, atmospheric, reactor and accelerator neutrino studies. The discovery of oscillations, detection of 19 neutrino events from supernova 1987a by the old IMB and Kamiokande water cherenkov detectors confirmed the theory of supernova explosions. The WMAP experiment has started to see imprints of neutrino mass effects on cosmic microwave back ground radiation left from the Big Bang.

2. Introduction

In 1998 Dr. Zohreh Parsa started the Neutrino CP Violation studies, extra Long Baseline (L, 2000 km < L < 4000 km) Neutrino (LBN) oscillation Physics and Experiment (LBNE) that envisioned sending a very intense neutrino (ν) beam (e.g., from Brookhaven National Laboratory on Long Island, New York), through the earth to a far away underground multipurpose large detector capable of making precision measurements of all the (ν) neutrino oscillation parameters, Proton decay and observation of natural sources of neutrinos such as supernova, providing a major advances in neutrino science. The key to this approach is (extra long) very long distance L. Length of the Baseline defines the physics you can do, once chosen, can not be changed without establishing a new facility.

Extra Long Base lines provide possibility of observing multiple nodes of the Neutrino oscillation probability in appearance and disappearance experiments. By measuring muon neutrino disappearance and electron neutrino appearance, such a project would be capable of determining all 3 generation mixing angles, mass hierarchy, along with magnitude of the CP violation (e.g., by measuring CKM phase and explicitly observing differences in the muon neutrino and muon anti-neutrino oscillations). No existing experiment so far has such capability. E.g., Neutrinos emitted in the first few seconds of a core-collapse supernova, would have insight into evolution of the universe. LBNE (very Long Baseline Neutrino Experiment), would be capable of measuring, (collecting and analyzing), the high-statistics neutrino signals from a supernova in our galaxy; provide information on the inside of the newly-formed neutron star; allowing possible observation of black hole creation.

"Very" or "Extra" Long Baseline terms has been used, to distinct our very Long Baseline (L) from other existing/ or proposed experiments that use the term "Long Baseline Neutrino Experiment (LBNE)" but have a short baseline, (e.g. Japan's Super-k Detector with baseline of less than 300 km, etc). In existing experiments, Detector(s) were placed at the first node of oscillations (with short baseline). But with extra long baseline LBNE, Detector(s) can be placed e.g. at the 2nd or third nodes of oscillations, that would allow the CP violation measurement in addition to the mixing angles, etc.     In some of our earlier simulation(s), L (lower bound) was reduced from 2000 km to 1300 km to correspond to baseline of FNAL to Homestake.

2.1. Neutrinos

Neutrinos are neutral subatomic particles that rarely interact with matter. Over trillion neutrinos pass through your bodies per second without leaving a trace. Neutrinos have low masses compared to other elementary particles. These tiny particles with no electric charge are able to oscillate, and change from one type of neutrino to another, when studied at LBNE (DUNE) could provide a deeper understanding of our universe.
 Neutrinos come in three states, or flavors, and can transform from one flavor into another; and that each neutrino flavor state is a mixture of three different nonzero mass states. Neutrinos come from nuclear reactions in stars, our sun, and on Earth. Three flavors are: electron, Muon and tau Neutrinos, where muon is 200 times heavier than the electron and tau is 3,500 times heavier. Neutrinos emitted in the first few seconds of a core-collapse supernova carry the potential for insight into the evolution of the universe. Results from the experiment should enable a broad exploration of the three-flavor model of neutrino physics, help understand matter-antimatter asymmetries (through charge-parity symmetry violation (CPV)) in neutrino flavor mixing; unravel the mystery of matter generation in the early universe; neutrino mass ordering; and precise measurement of neutrino mixing parameters. Grand unified theories (GUTs), predict rates for proton decay that cover a range directly accessible with the next generation of large underground detectors.

3. LBNE (very Long Baseline Neutrino Experiment)
     with Neutrino Source at BNL

Using a wide band muon neutrino beam from BNL to an underground (e.g., 0.5 megaton water Cherenkov) detector at Homestake gold Mine in South Dakota was one of our first study for "very Long Baseline Neutrino Experiment" (LBNE). Interest in LBNE with neutrino source at BNL to a far away (L=2540 km), underground Detector at Homestake, grew. Dr. A. Mann (U.Penn.) was one of the 1st to ask Dr. Parsa, (with his calls and in person), for her results for sending neutrinos (neutrino beam) from BNL (AGS) to the underground detector(s) in Homestake Gold Mine. He and others became increasingly interested; worked hard to get fundings for water removal and for Processing the Mine to an Underground Science Lab ("NUSL"; "DUSEL" etc.). Examples of Earlier simulations given in Fig.1 & Fig.2:

This page include part of Dr. Parsa's collaborative work. In addition to Dr. Parsa, later Dr. Marciano (BNL), and at Snowmass meeting (experimentalists) Drs. K. McDonald (Princeton U.), S. Kahn (BNL), and others joined the proposed (Extra) Very "Long Baseline Neutrino Experiment" (LBNE), that could search for CP violation in the lepton sector and precision studies of the neutrino mixing matrix and more. Years later, a BNL associate director (at that time) formed a group to look into AGS, neutrino source at BNL etc... With time the LBNE Collaboration expanded to an international collaboration and LBNE to a mega-science project.

Potentials of intense neutrino beams from BNL and FNAL to (Long Baseline) underground Detectors at Homestake, SD; Henderson, CO; Cascades, WA; etc., were also investigated and studied as competition for Deep Underground Science and Engineering Laboratory Site increased. Later Homestake, S.D. was selected.

Interest for LBNE in U.S. with neutrino source at BNL to a far Detector (underground at the Homestake, S.D L=2540 km), grew to fundamental high priority international mega-science project for over a decade, as "LBNE Collaboration" continued to expand. According to BNL Director at the time, BNL received funding from DOE to start the LBNE with Source at BNL, but (P. Paul said) he "had to return the money back to DOE" due to conflict of AGS chair (retired) who wanted more funding...

3.1. Neutrino Detector

Neutrino detector is an aparatus/ structure used to detect and study neutrinos. Since neutrinos interact weakly with other particles, Neutrino detectors are made very large to detect a large number of neutrinos. To block the background radiation and cosmic rays, they are placed underground. There are various detectors (See Top Links- e.g. "Detectors-Photos"), including: Super Kamiokande a large volume of water surrounded by phototubes that look for the Cherenkov radiation emitted when an incoming neutrino generates an electron or muon in the water; Sudbury Neutrino Detector uses heavy water as the detecting medium. Other detectors may have large volumes of chlorine or gallium that are periodically checked for excesses of argon or germanium, respectively, which are created by neutrinos interacting with the original material. MINOS uses a solid plastic scintillator surrounded by phototubes; Borexino uses a liquid pseudocumene scintillator also surrounded by phototubes; The Daya Bay Reactor Neutrino Detector walls are lined with photomultiplier tubes (PMTs), the tubes are designed to amplify and record flashes of light that signify an antineutrino interaction. The acoustic detection of neutrinos is done by ANTARES, IceCube, and KM3NeT collaborations; etc.

4. LBNE Reconfiguration    click

Following sections include a brief chronology of LBNE Reconfiguration with Neutrino Source at FNAL, (The Deep Underground Neutrino Experiment), DUNE/LBNF development(s) etc. "Top Links" provides more on LBNE and for beam to Detector at SURF (DUNE/LBNE); also on Reactor Experiment; Solar Neutrino Experiment; etc.    In 2012, Fermilab (FNAL) proposed for the LBNE with source at FNAL. Phase-I (CD-1) was approved by DOE which included construction of a Neutrino beamline at FNAL, where the Neutrino beam would travel through earth to a far detector at Sanford Lab in Lead, S.D. |Click Here|. For Brookhaven National Laboratory, DOE's approval of CD-1 was an important milestone after over decade of LBNE work at BNL. Using a high intensity accelerator neutrino beam from FNAL to a, (L=1287.475 km or about 800 miles baseline) liquid Argon TPC detector at |SURF| (Homestake), is the LBNE reconfiguration. This program goals, (are the BNL LBNE physics goals that started over a decade earlier), include Determination of leptonic CP violation, v mass hierarchy, underground physics etc.   LBNE with source at FNAL later was renamed Deep Underground Neutrino Experiment (DUNE). LBNE Collaboration became DUNE Collaboration.

     5. DUNE/ LBNF  

    The Deep Underground Neutrino Experiment (DUNE) expected to use the most intense neutrino beam and a larg detector to study neutrino (v) the most abundant matter particles in the universe. Scientists continue working to discover the missing pieces that could explain e.g., how the known particles and forces created in our universe; discover if neutrino is the reason our matter-filled universe exists, to check formation of black hole in a nearby galaxy; proton decay, etc. The full-size DUNE Detector, expected to be built about a mile underground at the Sanford Research Facility (in homestake, South Dakota). Detectors record particle tracks emerging from rare neutrino collisions with (massive target material) atoms. For more on Detectors |click Here|.

These first results “show that the ProtoDUNE-SP detector works even better than was anticipated. DUNE co-spokesperson Stefan Söldner-Rembold, said: "Now we are ready for the construction of 1st components for the DUNE detector, which will feature detector modules based on this prototype, but 20 times larger. We are happy with the 1st physics results published; as some of our DUNE members (from BNL) delivered Components for the Proto-DUNE Detector. E. Worcester, BNL said “the ProtoDUNE results show that we have designed a detector that will allow us to reach our science goals in DUNE"; etc. This first DUNE paper, show how they were able to achieve a signal-to-noise ratio of 50 to 1, which previously could not achieve for liquid-argon time projection chambers. They also evaluated detector’s reliability and found more than 99% of its 15,360 detector channels are functioning as they should.
