Museum’s Spring into Science career expo a "huge success"

In a large, open space in the northwest wing of Chicago’s Museum of Science and Industry, scientists and engineers staffed tables that lined the room. With their science demos in place and smiles on their faces, they welcomed more than 1,000 people to the museum’s Spring into Science career expo on Saturday, May 21.

“The event was a huge success,” said Lizza Igoe, education coordinator at the museum and event organizer, in an email to the volunteers. “[Everyone] thoroughly enjoyed learning about different career opportunities in the fields of science, technology, engineering and medicine, as well as getting a glimpse into the working world.”

Fermilab’s Mike Albrow, a particle physicist, and Linda Purcell-Taylor, a senior technician, volunteered at the event.

Purcell-Taylor placed a secondary emission monitor, also known as a beam profile monitor, on the Fermilab table.

The round, metallic device has a 4-inch diameter hole through the middle, which allows the particle beam to pass through. At the push of a button, a wire mesh material moves into the pathway of the particle beam. As particles pass through the mesh, they interact with the wires and create electrical signals that are collected and processed by a computer.

“This is part of a system we use to see the shape of the beam and where it is going through the beamline so that we can adjust magnets to steer it,” Purcell-Taylor explained to a group of girls from Sawyer Elementary School in Chicago, who crowded around the table to take a look.

One of the girls, Giselle Castañeda, a sixth grader, said she is part of the science club at her school and wants to be a teacher when she grows up. Castañeda and her friends jotted down notes as Purcell-Taylor talked about her job.

“I like that every day I’m learning something new about science,” Purcell-Taylor said to the girls.

Albrow also captured the students’ attention with a real-time cosmic ray detector. The device, which is about the size of a narrow shoe box and is filled with plastic particle-detecting fibers, was connected to a camera that transmitted the image to his laptop.

Fixed on the future

From The Antarctic Sun, May 27, 2011

South Pole Telescope repair ensures experiment will continue to probe mysteries of the universe.

The South Pole Telescope is a bold experiment attempting to answer some of the big questions in cosmology, such as the nature of dark energy, a mysterious force that pervades the universe.

The 10-meter telescope, built during the 2006-07 field season at the U.S. Antarctic Program’s South Pole Station, has already made some big discoveries, such as detecting the most massive high-redshift galaxy cluster to date.

But the latest feat involving the project is one researchers have no wish to repeat.

For a few tense days during the 2010-11 season, about half of the instrument was jacked up more than a meter in the air to repair the azimuth bearing, which allows the instrument to turn side to side — an important function for an experiment scoping the southern sky.

LPC scientists help reveal quark gluon plasma properties

Scientists from the LHC Physics Center at Fermilab recently helped to uncover further evidence of a state of matter scientists tie to the birth of the universe.

Their research gives scientists new insights into the properties of quark gluon plasma, a state of matter physicists think existed split seconds after the Big Bang.

Members of the LPC worked with heavy ion physicists at CERN and at Ecole Polytechnique in Paris to complete the research in about a month.

“From the first plot to the paper in four weeks was a remarkably short time,” said LPC physicist Ian Shipsey. “The seven-hour time difference produced a communication challenge but also an opportunity to work around the clock.”

In the world we observe today, quarks are bound with other quarks and gluons. The quark gluon plasma is an unusual state of matter in which single quarks and gluons float free. The exotic material is more than 100,000 times hotter than the inside of the sun and denser than a neutron star.

The LPC physicists and their collaborators found that the quark gluon plasma seemed to break apart composite particles called upsilons, which are made up of bottom quarks and their antiparticles. The upsilons studied here come in three states: one tightly bound state and two less tightly bound excited states.

CMS scientists observed that a larger fraction of the upsilons they detected in 2.76 TeV heavy ion collisions, as opposed to proton-proton collisions at the same energy, were in the tightly bound state. Scientists such as Shipsey hope that the observation can provide them with information about the temperature of the quark gluon plasma, a fundamental parameter necessary to learn more about this state.

“To be part of CMS at this time is the greatest privilege of our careers,” he said. “This is just the beginning. The best is yet to come.”
