Fermilab mentors offer IMSA students the finishing touch

IMSA students (left to right): Je-ok Choi (Fermilab mentors Young-Kee Kim and John Yoh), Anita Mehta (Niki Saoulidou), Jennifer Iglesias (Mark Fischler), Susan Dittmer (Jane Nachtman), Forrest Iandola (Mike Syphers), Angela Suh and Stephanie Bian (both mentored by Young-Kee Kim and John Yoh. Not pictured: Monica Bhattacharya (Gina Rameika), Birce Onal (Richard Schmitt), and Parker Schmitt (Niki Saoulidou).

On April 26, thirteen gifted high school students offered presentations to culminate their year-long research projects under the mentorship of Fermilab scientists. The students gave 15 minute talks and presented posters across disciplines at their school in Aurora. They were among 250 Illinois Mathematics and Science Academy students who participated in the IMSA mentorship program the past year.

IMSA has a long-established program of student mentorships at labs, museums, hospitals and other institutions throughout the Chicago area. Fermilab was one of the first organizations to participate in IMSA’s mentorship program, which began in 1989.

“In the early years finding mentors was somewhat ad hoc, by word of mouth or through contacts that students made with Leon Lederman’s help,” said program facilitator Marge Bardeen, manager of the Fermilab Education Office. “Also, students introduced their mentors to other students at the end of the year.”

Today, Fermilab and IMSA have support teams to match mentors with students. “It’s a great opportunity. Students get real world experience with world-class scientists,” said Judy Scheppler, IMSA coordinator of student research and inquiries.

CDF scientist Jane Nachtman tutored IMSA student Susan Dittmer this past year, working together each Wednesday on CDF physics simulations. Nachtman taught her the particle physics, detector science and other physics concepts required in the project. Nachtman said the work was at the level of an undergraduate student, but with the independence of a graduate student.

Susan’s IMSA report summarized her analysis of CDF dilepton events, looking for signs of new physics. “As a woman in physics," Nachtman said, "I think I should encourage other women to become physicists. Susan prepared her talk and poster completely on her own, and she did a great job.”

A Giant Takes On Physics' Biggest Questions


300 FEET BELOW MEYRIN, Switzerland - The first thing that gets you is the noise.

Physics, after all, is supposed to be a cerebral pursuit. But this cavern almost measureless to the eye, stuffed as it is with an Eiffel Tower's worth of metal, eight-story wheels of gold fan-shape boxes, thousands of miles of wire and fat ductlike coils, echoes with the shriek of power tools, the whine of pumps and cranes, beeps and clanks from wrenches, hammers, screwdrivers and the occasional falling bolt. It seems no place for the studious.

The physicists, wearing hardhats, kneepads and safety harnesses, are scrambling like Spiderman over this assembly, appropriately named Atlas, ducking under waterfalls of cables and tubes and crawling into hidden room-size cavities stuffed with electronics.

They are getting ready to see the universe born again.

Director's Corner

Investigating the dark world

Pier Oddone

The dark world is doing well here at Fermilab. Last week, the Fermilab Center
for Particle Astrophysics hosted
a symposium on dark matter. The vibrancy
of the community hunting for dark matter is palpable. Many researchers across the world are drawn to the hunt and many of them were here to share their ideas and excitement. At Fermilab we participate in this search along two avenues in a broadly collaborative effort with the HEP community.

The first avenue is to attempt to detect particles in the halo of our galaxy using sophisticated detectors deep underground, and the second is by getting ready to produce dark matter particles with the LHC and detect them with the CMS detector. Either one of these avenues will pay off only if dark matter is made of massive relic particles left over from the Big Bang. Circumstantial evidence points strongly to the possible explanation of dark matter by the existence of WIMPS - a fortuitous acronym that describes a weakly interacting massive particle. Adding to our expectations, supersymmetric theories using totally independent reasons postulate the existence of these particles. And to top it all off, if these particles exist, they are likely to be produced at the LHC. Dark matter is surely around the corner!!

We have fewer prejudices about dark energy than about dark matter. While many clues point towards dark matter as being made of relic particles, we don't have a clue about what dark energy is. So we are left with studying the one effect that dark energy produces: the accelerating expansion of our present universe. We are only at the beginning of the quest to understand dark energy. The next step is to understand more precisely the rate of acceleration of the expansion, and how that rate might change over time.

At the beginning of this month a DOE and NSF review committee recommended proceeding with CD-1 approval of the Dark Energy Survey (DES), a broad collaboration in which Fermilab plays a leading part. The experiment will carry out a broad survey of the Southern sky using a modified telescope in Chile and a sophisticated CCD imager. The DES experiment will add to the knowledge of dark energy and will set the stage for even more ambitious projects in the next decade using satellites in space and larger telescopes on the ground.

In all of these projects, dark energy, dark matter and CMS, we benefit greatly from the extraordinary collaboration between DOE and NSF in support of the HEP community and the laboratory.
