cavity Archives

The blue cylinder in this diagram represents a superconducting microwave cavity used to accumulate a dark matter signal. The purple is the qubit used to measure the state of the cavity, either 0 or 1. The value refers to the number of photons counted. If the dark matter has successfully deposited a photon in the cavity, the output would measure 1. No deposition of a photon would measure 0. Image: Akash Dixit, University of Chicago

Sensitive qubit-based technique to accelerate search for dark matter

Fermilab feature

Quantum bits acting as particle detectors offer a fast and highly reliable means of solving one of the great mysteries in physics: the nature of dark matter. This new method promises a more efficient way to detect dark matter candidates by improving the experimental signal-to-noise ratio.

Testing wraps up for first Fermilab-designed cryomodule for PIP-II accelerator

Fermilab feature

A Fermilab team has completed tests for a crucial superconducting segment for the PIP-II particle accelerator, the future heart of the Fermilab accelerator chain. The segment, called a cryomodule, will be one of many, but this is the first to be fully designed, assembled and tested at Fermilab. It represents a journey of technical challenges and opportunities for innovation in superconducting accelerator technology.

HL-LHC Accelerator Upgrade Project receives approval to move full-speed-ahead from Department of Energy

Fermilab feature

The U.S. Department of Energy has given the U.S. High-Luminosity Large Hadron Collider Accelerator Upgrade Project approval to move full-speed-ahead in building and delivering components for the HL-LHC, specifically, cutting-edge magnets and accelerator cavities that will enable more rapid-fire collisions at the collider. The collider upgrades will allow physicists to study particles such as the Higgs boson in greater detail and reveal rare new physics phenomena. The U.S. collaborators on the project may now move into production mode.

Fermilab attains unprecedented quality factor for LCLS-II accelerator cavity

Fermilab feature

Members of Fermilab’s Technical Division recently achieved a record-high quality factor with a fully dressed cavity for a SLAC-headed project, Linac Coherent Light Source II.
