[5][6] Ongoing neutrino experiments are ICARUS (Imaging Cosmic and Rare Underground Signals) and NOνA (NuMI Off-Axis νe Appearance).

This consortium is led by the 2007-2024 management group, the Fermi Research Alliance (FRA), with Amentum Environment & Energy, Inc., and Longenecker & Associates as new additions.

The gas is introduced into a container lined with molybdenum electrodes, each a matchbox-sized, oval-shaped cathode and a surrounding anode, separated by 1 mm and held in place by glass ceramic insulators.

[3] The new Linac site will be located on top of a small portion of Tevatron near the Booster ring in order to take advantage of existing electrical and water, and cryogenic infrastructure.

The measurements DUNE will make are expected to greatly increase the physics community's understanding of neutrinos and their role in the universe, thereby better elucidating the nature of matter and anti-matter.

Fermilab is continuing an experiment conducted at Brookhaven National Laboratory to measure the anomalous magnetic dipole moment of the muon.

The Brookhaven experiment ended in 2001, but 10 years later Fermilab acquired the equipment,[68] and is working to make a more accurate measurement (smaller σ) which will either eliminate the discrepancy or, hopefully, confirm it as an experimentally observable example of physics beyond the Standard Model.

[92] On September 1, 2023, Chief Research Officer Bonnie Fleming announced that the Fermilab accelerator system was temporarily shut down for safety reasons.

This resulted in an initial furlough of employees and closure of its operations and public access for one week in August---an action that added to the considerable strife at the laboratory.

[96] Despite this, Tracy Marc, head of Fermilab's media services, told WTTW News that "the overall financial health of the laboratory remains intact and is being managed".

For example, the first allegation concerning an egregious case of sexual harassment was reported in The Guardian[100] and the fact that the claimant had submitted a complaint to Fermilab which took no action appeared in court documents.

[95] In order for the whistleblowers to remain anonymous, the report was uploaded to the arXiv preprint server by Giorgio Bellettini, a respected leader in the field of particle physics who served as spokesman of the collaboration for the Collider Detector at Fermilab twice.

Significant procurement issues have hindered the laboratory's ability to successfully deliver efficient and effective business systems/resources to enable the Science Mission.

[109]   Thus, the selection leaves the scientific and human resources management unchanged, but does strengthen expertise to deliver large projects.

The lab failed to meet expectations in five out of eight categories, including two C+ grades in program management and contractor leadership and a C in business systems.

By spring 2023, the restrictions had become so onerous that more than 2500 physicists and visitors to the laboratory signed an "open petition to elected representatives to reopen Fermilab.

"[115] The petition stated that: "The access policy changes undermine critical aspects of the scientific process as well as the basic functioning of Fermilab.

Hosting research meetings, interviewing prospective employees, collaborating with scientists outside the lab, and enacting our famously impactful education programs have all been hindered."

In May 2023, Director Lia Merminga posted a response to the petition on the Fermilab website,[116] noting that some areas on site remain open to the public during specific hours with ID access requirements.

[120] Fermilab's first director, Robert Wilson, insisted that the site's aesthetic complexion not be marred by a collection of concrete block buildings.

The design of the administrative building (Wilson Hall) was inspired by St. Pierre's Cathedral in Beauvais, France,[121] though it was realized in a Brutalist style.

Wilson's sculptures on the site include Tractricious, a free-standing arrangement of steel tubes near the Industrial Complex constructed from parts and materials recycled from the Tevatron collider, and the soaring Broken Symmetry, which greets those entering the campus via the Pine Street entrance.

Also scattered about the access roads and village are a massive hydraulic press and old magnetic containment channels, all painted blue.

In 1967, Wilson brought five American bison to the site, a bull and four cows, and an additional 21 were provided by the Illinois Department of Conservation.

[123][124] Some fearful locals believed at first that the bison were introduced in order to serve as an alarm if and when radiation at the laboratory reached dangerous levels, but they were assured by Fermilab that this claim had no merit.

Today, the Fermilab bison herd is a popular attraction that draws many visitors[125] and the grounds are also a sanctuary for other local wildlife populations.

[128] Working with the Forest Preserve District of DuPage County, Fermilab has introduced barn owls to selected structures around the grounds.

[129] During running, particle beams produce tritium, an isotope of hydrogen consisting of a proton and two neutrons that is weakly radioactive with a half-life of 12.3 years.

[105] In particular, tritium produced in the NuMI beamline that sends neutrinos to experiments in Minnesota has been pumped into the industrial water cooling system that is used for equipment across the Fermilab campus.
