It takes a village

Building a particle physics laboratory requires more than physicists. Fermilab archivist Valerie Higgins has authored a paper available in the online physics repository arXiv, and earlier this month she published an op-ed for Physics World on the importance of capturing perspectives from all parts of the laboratory. She sat down with Symmetry writer Lauren Biron to discuss her thoughts.

First baby bison of the year born at Fermilab

On Saturday, April 20, baby bison season officially began. The first calf of the year was born in the early morning hours, and mother and baby are doing well. Fermilab is expecting between 12 and 14 new calves this spring, and all of our neighbors are welcome to come on site to see and photograph the newborns.

Spinning new targets for accelerators

Fermilab scientists are preparing for future, high-power particle beams with a technological advance inspired by spinning sugar. It’s a new type of target — the material that beams collide with to produce other particles, such as neutrinos. The target is designed to be able to withstand the heat from high-intensity beams, expanding the potential of experiments that use them. Researching this new patent-pending technology already has led to a TechConnect Innovation Award and might have applications in the medical field.

MINERvA successfully completes its physics run

On Feb. 26, a team on Fermilab’s MINERvA neutrino experiment gathered around a computer screen to officially conclude its data acquisition. Even with the data collection over, the work marches on. MINERvA now turns its attention to analyzing the data it has collected over the past nine years of its run.

Firing on all cylinders

It’s always great when every one of Fermilab’s nine particle accelerators are turned on and provide beam. With the lab again firing on all accelerator-cylinders, we thought it would be a good time to provide a rundown of each of the members of Fermilab’s accelerator complex. Get to know Fermilab’s suite of accelerators and storage rings.

Waiting for neutrinos

Particle detectors recorded neutrinos from supernova SN1987A hours before telescopes saw the first light. Thirty years later, scientists around the world are eager to detect neutrinos from another one. The international Fermilab-hosted Deep Underground Neutrino Experiment will be looking for them. These neutrinos can tell us more about supernovae themselves and may hint at new physics that could upend the Standard Model of particle physics.

To Ph.D. or not to Ph.D.

Respondents to Symmetry’s survey about what it’s like to earn a Ph.D. in particle physics or astrophysics offer their views of the experience. Nearly 2,000 people worldwide complete the scientific rite of passage each year. Yet for many people, the process remains mysterious.
The more than 300 responses to Symmetry’s survey described a challenging, multifaceted experience that goes far beyond job training, and even beyond the scientific goal of studying the fundamental nature of the universe.
