In Memoriam

In Memoriam: Dennis Theriot

Dennis Theriot, center, works with Bruce Chrisman and former deputy director Ken Stanfield on designing the One West conference room in 1993.

Dennis Theriot, a laboratory leader during the '80s and early '90s, died on July 5. He was 72.

Theriot retired from Fermilab in 1993 as associate director of technology. During his 24 years at the laboratory, he also served as head of the neutrino department and as the deputy project manager for CDF, which he was instrumental in designing and building.

Former Fermilab deputy director Ken Stanfield, who worked with Theriot during most of his career, remembers how Theriot brought his talent for managing very large enterprises to each assignment.

Theriot had oversight of conventional construction when John Peoples was laboratory director. Peoples credits Theriot's vision for the design of One West and the ground floor entrances to Wilson Hall, and the conversion of experimental facilities into an engineering center and the Silicon Detector Facility (SiDet).

"I fondly remember many heated and productive discussions on how to build the laboratory," Peoples said. "Dennis brought a passion and good humor to his work that few others had. He was one of the people who helped to build the Fermilab we love."

Theriot provided structure to both CDF's detector and to CDF's diverse and complicated international collaboration, said former Fermilab employee Roy Schwitters, who worked with Theriot on CDF and the Superconducting Super Collider.

"He well understood the physics we wanted to do with CDF, including assembling multi-hundred-ton objects into a precision instrument, and the foibles of physicists in trying to do so," Schwitters said.

Fermilab Chief Operating Officer Bruce Chrisman, who worked alongside Theriot as the associate director for administration, remembers Theriot as enthusiastic.

"Dennis was a great guy. He always brought well thought-out ideas to the table," Chrisman said.

Special Announcement

Dark Energy Survey announces new website

Astronomy was once the domain of the lone stargazer peering at the night sky. But modern experiments, such as the Dark Energy Survey, require more complex arrangements.

Learn more about DES through its new website. Hundreds of scientists taking part in the multinational collaboration will use a high-tech camera attached to a high-power telescope to study the stars. The new website explains the instruments and methods DES scientists will use in their research and the science behind the question they hope to answer: What is causing the expansion of the universe to accelerate?

U of M students building small-scale neutrino detector

From Minnesota Public Radio,
July 13, 2010

Minneapolis - Solving the unexplained mysteries of the universe may seem like a big goal for a research project, but that's exactly what scientists hope someday comes out of a work University of Minnesota students are doing this summer.

The students are building parts for a neutrino detector in a huge warehouse near the university's Twin Cities campus.

The detector is a smaller version of a six-story-high device that will be placed in an underground lab in northern Minnesota in few years.

From the Accelerator Division

Marsha Jo Hannah

Roger Dixon, head of the Accelerator Division, wrote this week’s column.

Roger Dixon

Many scientists remember when and why they began contemplating a career in science. I recently had the chance to reflect on the origins of my own scientific career and realized the special role that many women played in it. I was fortunate that my great grandmother was one of the first individuals licensed by the state of Wyoming to practice medicine, and my favorite role model at the laboratory is Helen Edwards, who hired me.

Today, however, I would like to focus on Marsha Jo Hannah. She was one of my undergraduate classmates at New Mexico Highlands University. Marsha Jo was brilliant. She obliterated the professors' notion of grading tests on a curve. For her, only the top possible score was relevant. If her solutions did not agree with the professor's, it usually meant the professor had made a mistake. I worked very hard to compete with her and considered myself successful whenever my name was uttered along with hers in a single sentence.

Marsha Jo was a very big factor in driving me to greater achievements in science. If it were not for her, I suspect I would have ended up as a huge rock star-or maybe something else.

In spite of my competitive nature, we were great friends. She was a math major, but she took all the physics classes with me just to keep me in my place. I pretended to have a second major in math. I'm not certain she noticed.

Of course I would like to think that I had an influence on her, and maybe I did. Toward the end of our time at Highlands, I decided to look for a good place to go for graduate school. Marsha Jo had decided to stay at Highlands for her graduate studies. When she noticed my wanderlust, she applied to a couple of out-of-state graduate schools. She was accepted at both places and chose to attend Stanford University. Three years later she had a Ph.D. in artificial intelligence while I was just beginning to build spark chambers for my thesis research.

Well, I never believed that stuff about women and mathematics, but I am admittedly fortunate to have encountered so many brilliant women in my career.

Safety Update

ES&H weekly report, July 13

This week's safety report, compiled by the Fermilab ES&H section, includes one DART injury and two first-aid only injuries. The DART case involved an employee who suffered a job-limiting back injury after moving steel tiebars from a vehicle into a building. The first aid-only injuries were both wasp stings. Find the full report here.
