At May 28, the XENON-collaboration has presented the latest results of the world’s largest and most sensitive detector for Dark Matter in the form of Weakly Interacting Massive Particles (WIMPs).
The XENON1T-detector collected an unprecedentedly large exposure of about 1 tonne x year with a 3D imaging liquid xenon time projection chamber. Results from XENON1T show that the WIMPs, if they indeed comprise the Dark Matter in our galaxy, will result in a rare signal, so rare that even the largest detector built so far cannot see it directly. These results will lay the foundation for further theoretical and experimental research on the subject.
The XENON1T has been operated by the international collaboration of more than 165 researchers from 27 institutions. Auke-Pieter Colijn, working as senior researcher at Nikhef and affiliated to Utrecht University and University of Amsterdam, is involved in this project.
