Evidence found for a new fundamental particle

If you’re fascinated by the weird world of particles — and who isn’t? — check out Fermilab’s newest website: All Things Neutrino. If you’re curious about what neutrinos are, where they come from, what their history is, and why scientists can’t stop studying them, look no further.

The new website has launched just in time for the biggest neutrino conference in the world, Neutrino 2018, where results from neutrino experiments at Fermilab and around the world will be presented. Neutrino 2018 takes place in Germany from June 4-9, and All Things Neutrino is the perfect companion to help understand the findings coming from the conference.

As the famous physicist Albert Einstein once said, “Education is not the learning of facts but the training of the mind to think.”

This year, SciTech Hands-On Museum, located in downtown Aurora, Illinois, celebrates 30 years of engaging minds of all ages. In 1988, founding director Ernest Malamud, a Fermilab physicist, envisioned an inspiring space to introduce people of all ages to STEM fields.

“We wanted to create a space that broke down the most basic tenets of science,” Malamud said. “Each exhibit would feature just one of these principles, for instance light and color, so visitors could learn the basics and, in that way, become engaged.”

In 1982, Malamud took a leave of absence from Fermilab to work at the world-famous Exploratorium, a STEM museum in San Francisco, planting the seed in his mind to create a similar space serving Chicago’s western suburbs. Then, in 1987, he wrote a proposal for what would become the first and largest hands-on science museum in the western Chicagoland.

While Malamud worked at Fermilab on Tevatron upgrades and experiments such as DZero in 1990, the city of Aurora granted him a lease for a former U.S. Post Office. Juggling the roles of both scientist and director, he realized he would have to choose. Fermilab’s director at the time, John Peoples, saw great potential in his vision. Even though it was unprecedented for a scientist at Fermilab to be assigned a position at a separate institution — a museum — Malamud was hired by Fermilab as director of SciTech. He served as the museum’s director for eight years and with museum volunteer Olivia Diaz, Fermilab, other research institutions and the community, built the museum from the ground up. After he returned to work as a scientist, Diaz took over the position of museum director.

In addition to designing engaging and innovative learning techniques, Malamud and Diaz envisioned an inclusive learning space and worked hard to reach underserved communities in the nearby counties.

“Very early on, we realized that the children in and around Aurora, especially in underserved communities, weren’t getting much exposure to STEM fields,” Diaz said. “Since they would become our future scientists and engineers, it was urgent for us to bring science to them, so we created programs that traveled to area schools.”

The museum still engages all facets of the local community by bringing in students and families with classroom visits, private parties, Scout classes, camps and more. By partnering with the community and other nonprofit organizations, SciTech is able to promote its programs by distributing free passes and scholarships.

Malamud and other Fermilab scientists have acted as the museum’s directors and helped as volunteers for many years. To this day, Fermilab is represented by a member on the museum’s Board of Directors.

“Fermilab has been with the museum all along and has been a great driver of its success,” Diaz said, “They helped give SciTech its start, and since then have been a major source of volunteers. Fermilab staff have served on the Board of Directors, created and built exhibits, served as scientist mentors, and participated in the creation of new and unique outreach programs.”

Since its humble beginnings, the museum has become a community staple, and Arlene Hawks, the museum’s current executive director, says that the number of field trips and outreach events are dramatically on the rise. About 75,000 visitors come to SciTech every year from across the western suburbs, and the museum plans to increase its reach. Right now, it’s captivating visitors with an interactive display sponsored by ComEd called “Smart Energy” and an exhibit sponsored by Molex that walks visitors through the science of fiber optics.

Hawks hopes partnerships and funding from Fox Valley businesses and organizations will continue to help the museum develop fresh, interactive STEAM (science, technology, engineering, arts and mathematics) exhibits. The arts are of particular importance to Hawks, who has a Ph.D. in theater and knows creativity and art can be used as vehicles to learn STEM subjects.

“We have a very hard-working staff, albeit it small, that puts so much passion and effort into Ernie’s dream to make science exciting and accessible for all,” Hawks said.

The museum has impressive plans for its future. Hawks hopes to someday build further exhibits for visitors interested in the natural sciences and refresh the museum’s interior with a more deliberate layout. To create a more welcoming atmosphere, the museum will install a water feature in the area leading out to Fox Motion Park, overlooking the Fox River, which runs through downtown Aurora. This new feature will include an interactive display focusing on the Fox River.

Hawks says she’s thrilled that the museum has thrived and grown with the support of community partners and the Board of Directors, keeping Ernie Malamud’s vision of exploring and discovering the sciences alive.

“I’m just delighted to have been sitting in the director’s chair for the last five years, about to celebrate our 30th anniversary,” Hawks said. “We are determined to carry on with the museum’s founding vision of nurturing the curiosity of both children and adults.”

The Oak Ridge Leadership Computing Facility and Fermilab are executing the integration of the Adaptive Input/Output System and the BigData Express high-speed data transfer service.

Projects large enough to run on high-performance computing (HPC) resources pack data—and a lot of it. Transferring this data between computational and experimental facilities is a challenging but necessary part of projects that rely on experiments to validate computational models.

Staff at two U.S. Department of Energy (DOE) Office of Science User Facilities — the Oak Ridge Leadership Computing Facility (OLCF) and Fermi National Accelerator Laboratory — facilitated this process by executing the integration of the Adaptive Input/Output System (ADIOS) and the BigData Express (BDE) high-speed data transfer service.

Now ADIOS and BDE developers are changing the way researchers can transport and analyze data by incorporating a new methodology into the tool that allows for compressing and streaming of data coming out of simulations in real time. The methodology is being tested by OLCF user C. S. Chang, a plasma physics researcher at Princeton Plasma Physics Laboratory (PPPL) who studies the properties of the plasmas that exist in giant fusion devices called tokamaks. Chang seeks an understanding of the power needed to run ITER and the heat load to the material wall that will surround its plasma, both of which are key to fusion’s viability. ITER is an international collaboration working to design, construct, and assemble a burning plasma experiment that can demonstrate the scientific and technological feasibility of fusion power for the commercial power grid. ITER, which counts DOE’s Oak Ridge National Laboratory (ORNL) among its partners, is currently under construction in southern France.

“If users can separate out the most important pieces of data and move those to another processor that can recognize the intended prioritization and reduce the data, it can provide them with feedback that they may need to stop a simulation if necessary,” said Scott Klasky, leader of the ADIOS framework and group leader for ORNL’s Scientific Data Group.

Wenji Wu, principal investigator of the BDE project and principal network research investigator of Fermilab’s Core Computing Division, added, “The new approach leverages the software-defining network [SDN] capabilities for resource scheduling and the high-performance data streaming capabilities of BDE.”

SDN allows users to dynamically control network resources rather than manually request to connect.

“This combination enables real-time data streaming with guaranteed quality of service, whether it be over short or long distances,” Wu said. “In addition, this approach yields small memory footprints.”

Although the project is still in the development phase, preliminary tests allowed Chang and his team to successfully transfer fusion data between the OLCF  — located at ORNL — and PPPL.

“With this new methodology, users can stream data on the network without ever touching the file system and request network resources on the fly,” said ADIOS and BDE researcher Qing Liu, who has a joint appointment with the New Jersey Institute of Technology and ORNL.

Without streaming capabilities, scientists can perform only after-the-fact analyses for many experiments, such as KSTAR, the Korean Superconducting Tokamak Advanced Research. But with simulations and experiments increasing in size, near–real-time monitoring and control are becoming necessary. The new ADIOS–BDE integration could also play a major role in large experimental projects, such as the fusion project Chang is leading and the Square Kilometer Array, an effort involving dozens of institutions to build the world’s largest radio telescope. The new streaming capabilities could more easily enable the capture of short-lived events such as pulsars — neutron stars that emit electromagnetic radiation — that the telescope aims to record.

“KSTAR wants to transfer their data as the experiment is happening, to process their data during the experiment,” Klasky said. “These additions to ADIOS will enable both sides to quickly perform data analysis and visualization in real time.”

Seo-Young Noh, director of the Global Science Experimental Data Hub Center at the Korea Institute of Science and Technology Information, leads a group that has contributed significantly to the BDE project.

“Our work has made cross-Pacific, real-time data streaming possible,” Noh said.

Klasky, Liu, and their collaborators will give a best paper plenary talk related to these new capabilities—titled “Understanding and Modeling Lossy Compression Schemes on HPC Scientific Data” — at the 32nd IEEE International Parallel and Distributed Processing Symposium. The team noted that the new ADIOS methodology will allow scientists to efficiently select the type of compression that will best fit their scientific and research needs, affording them the ability to analyze their data faster than ever before.

Liang Zhang, the developer of BDE data streaming capabilities, is working with Liu to enhance and test the tool. They expect the tool’s new capabilities to be fully tested and deployed by late 2019. This work also involves ADIOS researcher Jason Wang and BDE researchers Nageswara Rao, Phil DeMar, Qiming Lu, Sajith Sasidharan, S. A. R. Shah, Jin Kim, and Huizhang Luo.
