Description
The accelerator complex at Fermilab is currently undergoing improvements which will increase the available beam power to the complex and is known as Proton Improvement Plan-II (PIP-II). The PIP-II Linac is slated for operation near the end of this decade and will be the main proton driver for Fermilab experiments moving forward and provide the beam to LBNF/DUNE. However, the DUNE physics program requires only a fraction of the available protons provided by PIP-II and there are ideas to explore using the excess protons. The Accelerator Complex Enhancement, or ACE, will provide further upgrades in the 2030s in the form of increased power to LBNF along with a replacement for the Fermilab Booster which could also include an accumulator ring. The Fermilab Facility for Dark Matter Discovery (F2D2) is a proposed PIP-II beam dump facility to search for dark sector physics across detector threshold energy scales. F2D2 will have world-leading sensitivity to accelerator-produced dark matter, millicharged particles, and axion-like particles, which are produced in proton collisions with a fixed target. In this talk, I will summarize the physics possible at F2D2, present sensitivities to different dark sector physics and other beyond the Standard Model searches, and discuss the next steps towards realizing a beam dump program at PIP-II.
