The vast majority of US funding for the US LHC program directly supports US scientists and US institutions. It enables the US research community to:

• Perform research
• Operate detectors
• Maintain the computing infrastructure
• Process data
• Design and build detector and accelerator components

The US-CERN research programs are supported by:

• The US Department of Energy, Office of Science
• The National Science Foundation

These two federal agencies are responsible for:

• Developing a budget request based on US scientific priorities
• Executing the Congressionally-approved budget through contracts, cooperation agreements and grants to US scientists and institutions.
• Conducting regular project and grant reviews

The High Energy Physics budget request—which supports joint US CERN projects—is developed by the US Department of Energy and the National Science Foundation with guidance from the High Energy Physics Advisory Panel, an advisory committee that produces periodic reports outlining funding priorities for US particle physics investments.

Congress considers the request through its Congressional appropriations process, and then allocates funding to the agencies.

The agencies, in turn, execute the request by distributing the allocated funds to the appropriate US institutions and scientists.
