Landscapes through the eyes of three Illinois artists; reception on Dec. 12 at 5 p.m.

Melanie Brown's "Song Path" is currently on display in the Fermilab Art Gallery.

Humans have painted landscapes for centuries, transporting the viewer into a scene or drawing out of the scene remarkable qualities that are often not immediately apparent.

The paintings currently on display in the Fermilab Art Gallery exhibit impressive features of landscapes as understood through the senses, memories and imaginations of three artists. A reception for the artists featured in "Imagined Landscapes" takes place on Friday, Dec. 12, at 5 p.m. in the gallery.

Chicago artist Melanie Brown paints her acrylic landscapes with some element of improvisation, she said. In some, she responds to the material she works with, and in others, she reacts to a piece of music, the "Song Path Project" by Ryan Ingebretsen, that itself incorporates the natural sounds of a Minnesota landscape.

"You can hear the shape of the land in that piece," Brown said. "When I'm painting, it's similar: The painting becomes a landscape, but I'm not trying to capture one particular scene. It's more of an arriving. Each landscape has its own life in relation to how the image is built."

In Suzanne Keith Loechl's series titled "Earth" and "Unseen," layers of paint convey landscapes' rich histories — layers of growth, decay and renewal in a single plot of land.

"Like people, the landscape reinvents itself," Loechl said in an artist statement. "It heals when it's wounded, but sometimes it scars for life. Elements of the whole are nurtured or rubbed away."

Washes of color and shape — sometimes distinct from each other, sometimes blurred — in the landscapes of Chicagoland artist Julian E. Williams Jr. reflect an imagining of landscapes whose real-life details are lost to the overall impression made by the scene.

"For me, painting this way allows for interesting ambiguities that don't occur as when painting on location or from photographs," Williams said in a statement. "The results are veils of transparencies against various opacities, which eventually appear in an ethereal, meditative sort of space."

You can meet the artists in an artist talk in the gallery on Wednesday, Dec. 17, at noon.

In memoriam: James Thompson

Fermilab retiree James Thompson passed away on Dec. 4. He worked as the laboratory's employment manager and retired in 1998 after serving Fermilab for 30 years.

A memorial service will be held on Saturday, Dec. 13, following a fellowship reception. The fellowship will take place from 10-11 a.m., and the memorial service will begin at 11 a.m. The services will be held at Progressive Baptist Church, 275 Barnes Road, Aurora.

ICARUS on the road

From, Dec. 10, 2014

Last night ICARUS, the world's largest liquid argon neutrino detector, left the Gran Sasso Laboratory of the Italian Institute for Nuclear Physics (INFN) and is now on its way to CERN (European Organisation for Nuclear Research) in Geneva. Since 2010, ICARUS T600 – that is its full name — has been observing the neutrino beam sent from CERN to the Gran Sasso underground laboratories passing through 730 km of the Earth's crust. Now ICARUS has been carefully loaded onto two special equipment transporters and is being transferred to CERN to be overhauled and upgraded, in view of its probable future use in the United States. Physicists believe it is an essential and as yet inimitable element for an experiment with low-energy neutrinos at Fermilab in Chicago.

Balloon with a view

From The Economist, Dec. 6, 2014

Meet ANITA. Strictly, ANITA III — for she is the third iteration of the Antarctic Impulsive Transient Antenna. Her job, when she is launched sometime in the next few days, will be to float, suspended from a giant balloon, over Antarctica's ice, in order to record radio waves which that ice is giving off. These radio waves are generated by neutrinos passing through the ice, making Antarctica the biggest neutrino-detection laboratory in the world.

How to make a neutrino beam

Ingredients for a neutrino beam: speedy protons, target, magnetic horn, decay pipe, absorbers. Image adapted from Fermilab

Read the full column on neutrino beamlines.

Fermilab is in the middle of expanding its neutrino program and is developing new detectors to study these ghostly particles. With its exquisite particle accelerator complex, Fermilab is capable of creating very intense beams of neutrinos.

Our neutrino recipe starts with a tank of hydrogen. The hydrogen atoms are fed an extra electron to make them negatively charged, allowing them to be accelerated. Once the charged atoms are accelerated, all of the electrons are ripped off, leaving a beam of positive protons. The protons are extracted into either the Booster Neutrino Beamline (BNB) or are further accelerated and extracted into the Neutrino Main Injector beamline (NuMI). Fermilab is the only laboratory with two neutrino beams. Our two beams have different energies, which allows us to study different properties of the neutrinos.

In the BNB, these protons smash into a target to break up the strong bonds of the quarks inside the proton. These collisions are so violent that they produce new quarks from their excess energy. These quarks immediately form together again into lighter composite short-lived particles called pions and kaons.

Since the pions and kaons emerge at different directions and speeds, they need to be herded together. As a bugle tunes your breath into musical notes, a horn of a different type rounds up and focuses the pions and kaons. The BNB horn looks roughly like the bell of a six-foot long bugle. It produces an electric field that in turn generates a funnel-like magnetic field, which directs all of the dispersed pions and kaons of positive electric charge straight ahead. Particles with negative charges get defocused. By switching the direction of the electric field, we can focus the negatively charged particles while defocusing the positive charges.

The focused particles in the BNB beam travel through a 50-meter long tunnel. This is where the magic happens. In this empty tunnel, the pions and kaons decay in flight into neutrinos, electrons and muons. At the end of the decay tunnel is a wall of steel and concrete to stop and absorb any particle that is not a neutrino. Because neutrinos interact so rarely, they easily whiz through the absorbers and on towards the experiments. And that’s the basic formula to make a beam of neutrinos!

A single neutrino beamline can support many experiments because the neutrinos interact too rarely to get “used up.” The BNB feeds neutrinos to MicroBooNE, and most of them go on through to the other side towards the MiniBooNE detector. Similarly, most of those go on through the other side as well and continue traveling to infinity and beyond. Detectors located in this beam measure neutrino oscillations and their interactions.

On Monday, members of the National Accelerator Laboratory Women's Organization met for tea in the Fermilab Art Gallery.

NALWO is a longstanding part of the Fermilab community. The organization conducts outreach activities and hosts recreational events. NALWO gatherings such as the winter tea provide women at Fermilab and their families with an opportunity to socialize and enjoy the company of others.
