detector technology

Results from the ProtoDUNE single-phase detector at CERN pave the way for detectors 20 times larger for the international Deep Underground Neutrino Experiment, hosted by Fermilab.

From Pesquisa, November 2020: The FAPESP scientific director shares how he encouraged behaviors that helped improve research in São Paulo. With FAPESP encouragement, researchers in Brazil have held leadership positions in international collaborations, including in a photon detection system called Arapuca. Arapuca is a technology used in Fermilab’s Short-Baseline Near Detector and a baseline technology for the international Deep Underground Neutrino Experiment, hosted by Fermilab.

Magnets play a key role in looking for the direct transformation of muons into electrons, a theorized phenomenon that Fermilab’s Mu2e experiment will hunt for when it comes online in 2023. In an important milestone, seven essential magnets have passed testing and been accepted for the construction of the experiment.

Fermilab plays a key role in the Quantum Science Center, led by Oak Ridge National Laboratory. The center unites Oak Ridge’s powerhouse capabilities in supercomputing and materials science with Fermilab’s world-class high-energy physics instrumentation and measurement expertise and facilities. Drawing on their experience building and operating experiments in cosmology and particle physics and in quantum information science, the Fermilab team is engaging in QSC efforts to develop novel, advanced quantum technologies.

From APS Physics, Oct. 20, 2020: The SENSEI dark matter detector provides world-leading sensitivity for distinguishing lightweight dark matter from background noise.

A precise calibration for measurements of electric current has long eluded scientists. Last year, the ampere was redefined based on the charge of a single electron. The next generation of charge-coupled devices, known as skipper CCDs, could provide the sensitivity needed to calibrate the new definition.

From NIST, Oct. 13, 2020: Researchers at NIST and their colleagues, including Fermilab scientist Gordan Krnjaic, have proposed a novel method for finding dark matter. The experiment, in which a billion millimeter-sized pendulums would act as dark matter sensors, would be the first to hunt for dark matter solely through its gravitational interaction with visible matter. A three-minute animation illustrates the new technique.

Scientists are testing the components and systems for the international Deep Underground Neutrino Experiment, hosted by Fermilab, with other liquid-argon particle detectors. One such detector is ICEBERG, which is over 10,000 times smaller than DUNE will be. ICEBERG’s measurements are providing insight for future neutrino experiments.

Tiffenberg shares the $100,000 prize for advances in dark matter detection technology. He and collaborators on the SENSEI experiment drove the development of innovative sensors called skipper CCDs, which are sensitive enough to be able to pick up signals from dark matter particles of low mass.

Sensors for the world’s largest digital camera have snapped their first 3,200-megapixel images at SLAC. Crews at the SLAC National Accelerator Laboratory took the photo with an extraordinary array of imaging sensors that will become the heart and soul of the future camera of Vera C. Rubin Observatory.
