What is the identity of dark matter?
Professor Cabrera’s group sends detectors deep underground in the Soudan Mine in northern Minnesota to search for evidence of weakly interacting massive particles, or WIMPs. If WIMPs are the dark matter, they forced the formation of structure in the universe and they are responsible for the formation of galaxies, of solar systems, and of life. Working on an international project called the Cryogenic Dark Matter Search (CDMS II), Professor Cabrera and colleagues from 19 other institutions seek to determine whether WIMPs make up the unidentified portion of the universe referred to as dark matter. Their search is the major effort in the United States, and is the most sensitive experiment of its kind in the world. Professor Cabrera is Spokesperson for the next generation SuperCDMS experiment, which is being built and plans to operate in the three times deeper SNOLAB in Sudbury, Canada.
The Cabrera group builds detectors not only for dark matter searches, but also for X-ray spectroscopy and single photon detection from the near infrared through the optical bands into the ultraviolet bands. All these detector technologies operate at temperatures below 1.0 Celsius degree above absolute zero using superconductivity and cryogenic techniques.
