petition to elected representatives to reopen Fermilab." 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." With respect to the general public, the petition stated: "Today, the general public is only permitted to access the main road, and with ID requirements that are becoming increasingly stringent, soon its doors will be closed to tourists and even to some immigrants. We can no longer drive or bike around the premises freely. The dog park, Wilson Hall with its exhibits on the top floor, and other areas are no longer generally accessible. Fishing and other activities open to the public have been canceled." The petition emphatically requested that access policies be reverted to the open laboratory model that governed the laboratory prior to 2020.

DOE expects that this competition will elicit new and innovative approaches for planning the Laboratory's future." At an informational meeting for potential bidders on March 1, 2023, the presentation slides expanded upon issues under "Major Challenges/Risks" including highlighting the concern: "The Laboratory continues to have challenges in Financial Management and Acquisition Management. Audits repeatedly highlight the same deficiencies and control failures year after year. Any corrective actions implemented have resulted in little to no progress. Significant procurement issues have hindered the laboratory's ability to successfully deliver efficient and effective business systems/resources to enable the Science Mission. Substantial concerns remain regarding the ability to expend Government funds in an effective, efficient, and compliant manner."

On March 31, 2022, James Siegrist, associate director for High Energy Physics in the Department of Energy Office of Science, who had overseen the response to the P5 report, stepped down. In September 2022, it was announced that deputy director for Research Joseph Lykken would step down, to be replaced by Yale Professor Bonnie Fleming, who previously served as Deputy Chief Research Officer for the neutrino program at Fermilab. Regina (Gina) Rameika joined the DOE's Office of Science as the associate director for the Office of High Energy Physics in his place on November 7, 2022, moving from her role as spokesperson of the DUNE Experiment. 5030: 629: 617: 5706: 790: 657: 605: 6207: 363:(URA); although in 2023, the Department of Energy (DOE) opened bidding for a new contractor due to concerns about the FRA performance. On July 15, 2024, during the bidding process for the new contract, "whistleblowers" published very serious allegations against FRA management on a public physics preprint server. The detailed 108 page report accused the FRA of cover-up of cases of sexual harassment, attacks by employees, guns brought to site, and a major equipment failure. There has been no public response by the FRA or Fermilab Leadership since the appearance of the report. 401: 641: 701: 681: 236: 1480: 1144: 669: 745: 912:). The LPC offers a vibrant community of CMS scientists from the US and plays a major role in the CMS detector commissioning, and in the design and development of the detector upgrade. Fermilab is the host laboratory for USCMS, which includes researchers from 50 U.S. universities including 715 students. Fermilab hosts the largest CMS Tier 1 computing center, handling approximately 40% of global CMS Tier 1 computing requests. On February 9, 2022, Fermilab's 736:

project is to refurbish and replace 40 year-old Booster cavities. Many cavities have been refurbished and tested to operate at 15 Hz. The completion of cavity refurbishment is expected in 2015, after which the repetition rate can be gradually increased to 15 Hz operation. A longer term upgrade is to replace the Booster cavities with a new design. The research and development of the new cavities is underway, with replacement expected in 2018.

This would have required moving the existing Linac up 50 metres (160 ft). However, there were many technical issues with this approach. Instead, Fermilab is building a new 800 MeV superconducting Linac to inject to the Booster ring.
