How to make a neutrino beam

Neutrinos are elusive particles that are difficult to study, yet they may help explain some of the biggest mysteries of our universe. Using accelerators to make neutrino beams, scientists are unveiling the neutrinos' secrets. Image: Sandbox Studio

Neutrinos are among the most abundant particles in the universe, but they rarely interact with matter. Some of today's outstanding scientific mysteries, such as why there is more matter than antimatter in the universe, could be solved by studying neutrinos and detecting their interactions with matter.

Billions of neutrinos from natural sources, including the Sun, zip through every square centimeter of the Earth each second. Yet scientists cannot easily determine their initial type or exactly how far they traveled before reaching a detector.

To study neutrinos more effectively, scientists produce high-intensity neutrino beams using proton accelerators. Only a few laboratories in the world can manufacture such neutrino beams: the J-PARC laboratory in Japan, the research center CERN in Europe and Fermi National Accelerator Laboratory in the United States. Every two seconds, Fermilab fires a trillion neutrinos toward particle detectors located in northern Minnesota, more than 450 miles away. This intense beam produces about a thousand neutrino interactions per year in the detectors.

Scientists make high-intensity neutrino beams by starting with batches of protons from a bottle of hydrogen gas. They accelerate each batch to nearly the speed of light and smash it into a target, usually made of graphite or beryllium. The protons shatter the target's atomic nuclei and produce new particles, including short-lived pions—the source for neutrinos and anti-neutrinos.

Powerful focusing horns, which produce strong, carefully aligned magnetic fields, redirect the pions so they are all traveling in roughly the same direction, creating a meter-wide beam of either positively or negatively charged pions. Positively charged pions, which live for only a fraction of a second, decay into anti-muons and muon neutrinos; their equally short-lived, negatively charged brothers decay into muons and muon anti-neutrinos.

Blocks of aluminum, steel and concrete are the final steps to create a pure neutrino (or anti-neutrino) beam. The blocks stop and absorb all particles except the ghost-like neutrinos (or anti-neutrinos), which pass through unchanged. Ta da!

The experimental particle physics group at Syracuse University focuses on flavor physics using both heavy quarks and neutrinos, with a primary interest in identifying new sources of CP violation. It also has played leading roles in detector development for a variety of experiments. Currently we are busy helping to build components and work on construction for the MicroBooNE experiment at Fermilab, which will be the largest liquid-argon neutrino detector to operate in the United States. Our theoretical group focuses on phenomenology of the electroweak scale, building models of electroweak symmetry breaking, developing lattice field theory as a technique for studying a range of strongly coupled field theories and working on theoretical cosmology.

Our theoretical and experimental particle physics groups at Syracuse work on a broad range of topics and share a common goal of finding and explaining new physics. The experimental group has conducted and continues to conduct pioneering research in flavor physics and is active in all facets of HEP, including hardware, software and data analysis.

An insatiable appetite

Bill Pellico

Bill Pellico, head of the Proton Source Department, wrote this column.

Beam, beam and more beam—this is the sound of the Intensity Frontier calling the Proton Source of the Fermilab accelerator complex. What is the best, easiest and most economical way to answer the call? This is the challenge that we always need to address.

Fermilab is the only DOE high-energy physics facility with an accelerator program for the Intensity Frontier. Our success requires a robust accelerator complex capable of delivering intense beams of protons. At present, Fermilab has two proton beam lines that generate neutrinos for both short- and long-baseline neutrino experiments. Over the next decade, several other experiments will tap the proton spigot. Fermilab's plans for the Intensity Frontier require twice as many protons as we can currently deliver. How can we achieve this goal?

The construction of a multi-megawatt proton accelerator that delivers high-intensity beam is a long and expensive undertaking, particularly when budgets are tight. Fermilab's Proton Source, now more than 40 years old, will remain the workhorse for our laboratory in the near future and must be kept viable until it can be replaced.

We are in the middle of implementing the Proton Improvement Plan, which outlines vigorous upgrades to our existing proton accelerators. Recent changes under the PIP include the installation of the new RFQ injector line (which replaced the outdated Cockcroft-Walton system) and the Booster RF solid state upgrade (which will allow the radio-frequency power to pulse reliably at the Booster cycle rate of 15 Hertz.) In addition to meeting our PIP goals, these projects reduce the work needed to maintain antiquated equipment, improve Fermilab's technology base and give employees an opportunity to build and work on advanced accelerator hardware.

FY12 was the first year of implementing the PIP. Commissioning of the new RFQ injector and Booster RF systems will be completed very soon. Significant shutdown work is still under way and must be completed before the end of the current accelerator shutdown in the spring. But this is just the beginning.

In the last 10 years the Proton Source has achieved record beam intensities, with each year delivering more beam than it had provided in the first 30 years of its existence. The PIP plan is to double the proton beam intensity. But that won't be the end to improving our accelerator complex. Our efforts to ramp up the beam intensity, reliability and efficiency will be continuous because neutrino and muon experiments have an insatiable appetite for beam.

BOSS quasars unveil a new era in the expansion history of the universe

From Berkeley Lab News Center, Nov. 12, 2012

BOSS, the Baryon Oscillation Spectroscopic Survey, is mapping a huge volume of space to measure the role of dark energy in the evolution of the universe. BOSS is the largest program of the third Sloan Digital Sky Survey (SDSS-III) and has just announced the first major result of a new mapping technique, based on the spectra of over 48,000 quasars with redshifts up to 3.5, meaning that light left these active galaxies up to 11.5 billion years in the past.
