detector technology

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.

What is dark matter made of? Scientists at Fermilab are using ultrasensitive devices to look for the elusive particles that would explain the nature of dark matter. In this 3-minute video, physicist Javier Tiffenberg explains how a new detection technology, based on sensors known as skipper charge-coupled devices, or CCDs, provides a new way of looking for dark matter particles.

The skipper CCD instrument at the heart of scientist Javier Tiffenberg’s research shows promise for dark matter, neutrino detection and more. For the development of this forefront detector, Tiffenberg has won this year’s Universities Research Association Early Carer Award.

For a week spanning the months of July and August, scientists from around the world virtually gathered to attend the prestigious biennial ICHEP conference. At ICHEP, some of the most exciting physics results of the year are unveiled. CMS scientists from Fermilab and the LHC Physics Center were well-represented at the conference.

Scientists have begun operating the Dark Energy Spectroscopic Instrument, or DESI, to create a 3-D map of over 30 million galaxies and quasars that will help them understand the nature of dark energy. The new instrument is the most advanced of its kind, with 5,000 robotic positioners that will enable scientists to gather more than 20 times more data than previous surveys. Researchers at Fermilab helped develop the software that will direct these positioners to focus on galaxies several billion light-years away and are currently in the process of fine-tuning the programs used before the last round of testing later this year.

At the core of the mammoth detector assemblies and snugly surrounding the beam pipes are arrays of silicon sensors, which provide detailed patterns of interactions to micron-level precision, with subnanosecond timing and low mass. Research and development to improve the characteristics and develop better silicon detectors with the use of new technologies continue as we upgrade the existing detectors for better performance and develop designs for experiments at future generations of accelerators.
