Low Background
This array of Low Background detectors was built for the University of Washington and is used in one of the stations of the Advanced Photon Source at the Argonne National Laboratory. These detectors that have been designed to measure low energy x-ray events down to 0.75 keV. This is accomplished by careful selection and design of the low background and low noise components.
Ultra-Low Background X-Ray Detectors
Ultra-Low Background Units
The detectors used in the search for Dark Matter require special ultra low background NaI(Tl) material. The main contaminants of concern are: 238U, 40K, 232Th, 210Pb and total alpha rate. Over several years of research and development at ASI we achieved extremely radiopure material. Our ultra-low background NaI(Tl) material is called WIMPScint material. Our WIMPScint-III material is now being used in several Dark Matter experiments around the world. Refer to our data sheet for more details.
