Detectors in daily life

Not only are particle detectors essential to making discoveries in particle physics, they also play important roles in industry, science and medicine. Photo: Reidar Hahn

Ask someone what our world would look like if there were no cars or no telephones and they'll probably have an immediate answer. It's easy to imagine how our lives would be different without these things. But what if there were no particle detectors? Most people aren't sure what would change if these devices disappeared — even though particle detectors are at work all around us.

Particle detectors play a role in undertakings from drug development to medical imaging, from protecting astronauts to dating ancient artifacts, from testing materials to understanding the universe.

A particle detector is a device built to observe and identify particles. Some measure photons, particles of light such as the visible light from stars or the invisible X-rays we use to examine broken bones. Other particle detectors identify protons, neutrons and electrons — the particles that make up atoms — or even entire atoms. Some detectors are designed to detect antimatter. By sensing the electric charge and interactions of particles, the detectors can determine their presence, their energy and their motion.

It may seem like an esoteric task, but particle detection is a part of our everyday lives.

A chance of rain
Without particle detectors, climate models and weather forecasts would be a bit cloudy.

One of the most common tools used in modern weather forecasting is radar — radio waves sent through the air, bounced off of objects (such as rain drops) and collected by radio-frequency (RF) detectors. Using radar, scientists can gather information about the location, size and distribution of raindrops or other precipitation, as well as wind speed and direction and other variables. Some more advanced instruments apply the same technique using microwaves or lasers instead of radio waves. Radar is also a primary tool in the study of tornadoes and other severe storms, often with the goal of improving safety measures for people on the ground.

The Earth's climate — the long-term behavior of the atmosphere — is largely created by the interplay between two fluids: water and air. Fluids can be studied in detail in the laboratory using experimental devices that carefully track their complex motions using X-rays and other techniques that rely on particle detectors. Work done in the lab feeds into a growing understanding of our planet's complex climate.

At CERN European research center, the Cosmics Leaving Outdoor Droplets experiment, or CLOUD, is investigating the link between energetic particles from space, known as cosmic rays, and the formation of clouds in our atmosphere. The experiment suggests that the rays create aerosols, which act as seeds for new clouds. CLOUD scientists try to recreate atmospheric conditions inside a sealed chamber and use detectors to carefully monitor changes taking place. CLOUD's findings should help scientists better understand the effects of clouds and aerosols on Earth's climate.

The opportunity of a lifetime

From Rapid City Journal, Sept. 2, 2014

LEAD — Ten South Dakota students, including one from Hot Springs, were awarded special scholarships to study underground science for five weeks this past summer.

The Davis-Bahcall Scholarships for Underground Science, sponsored by 3M Company, paid the tuition and the room and board for the students to participate in a study program that took them to the Sanford Underground Research Facility in Lead, the Gran Sasso National Laboratory in Italy, Fermi National Accelerator Laboratory outside of Chicago, and other scientific facilities at laboratories and universities in South Dakota, Minnesota, Wisconsin, Illinois and Italy.

Kassia Symstad, a 2014 Hot Springs High School graduate, was chosen to participate in the program.

From the Deputy Director

It's all Πυθων to me

Joe Lykken

Nature is an analog computer with a bahzillion parts (bahzillion = much more than a zillion), so there are tremendous intellectual challenges in getting even the most powerful digital computers to emulate the processes that particle physicists are interested in. These challenges include making sense of the data from experiments, predicting what experiments should see, and simulating new accelerator and detector systems that will enable the experiments of the future.

Our Scientific Computing Division at Fermilab comprises almost 150 people with a unique and important cross section of skills, including scientists, engineers, software designers and software developers, as well as experts in using and operating high-performance and high-throughput computing hardware. Scientific Computing has always been a core strength of the laboratory, and SCD scientists are involved in all of the scientific endeavors at the lab. They have already played essential roles in major discoveries, including that of the Higgs boson.

Effective last week, Panagiotis Spentzouris took over as head of the Scientific Computing Division, relieving Rob Roser, who had been acting head even after assuming the role of Chief Information Officer for the laboratory. Panagiotis is a familiar face at the lab, having worked on four different experiments since arriving here in 1989. He has worn many hats for computing as well, and for the past 10 years has led a national collaboration called ComPASS (Community Project for Accelerator Science and Simulation). The vision of ComPASS, developing a common set of accelerator modeling tools that will enable large-scale virtual prototyping of accelerator components, was highlighted in the recent P5 report.

As U.S. particle physics moves forward on the P5 plan, Panagiotis will be charged with taking scientific computing to the next level. New paradigms in both computational and data-intensive computing are just around the corner, and how we bring these technologies together and take full advantage of them will require the kind of vision and energy that Panagiotis can provide.

As we congratulate Panagiotis on his new position of leadership, it's also a good time for those of us who have been calling him "Spentz" to improve our pronunciation skills in the mother tongue of Western civilization. Here is a link to help.
