Marc Schumann gave a talk (slides) Talk on April 3, 2017 at the occasion of the Scientific Committee meeting of our host laboratory LNGS, showing for the first time the exposure of our first dark matter run:
The ICARUS experiment just left Hall B at the Gran Sasso underground laboratory in Italy for its journey to CERN in Switzerland. We had designed the XENON1T water tank a bit smaller than originally planned to allow ICARUS to move past. Everything went smoothly, but it was a tight fit…
We wish our colleagues all the best with the future of their experiment. Read the full story of this move at interactions.org.
The XENON1T is shielded from ambient radioactivity by a large water tank that is equipped as a muon veto. The tank has a diameter of 10 meters and is 10 meters high. It is constructed from top to bottom and went up in the Gran Sasso underground laboratory within less than a month:
The XENON1T experiment has been approved by the INFN executive committee to be built in Hall B of the underground laboratory Laboratori Nazionali del Gran Sasso (LNGS) near Assergi, Italy. The experiment is designed to perform a search for Dark Matter with a sensitivity that is more than two orders of magnitude better than the current best sensitivities in the field.
XENON1T will contain more than 3000kg of liquid xenon that are instrumented as a two-phase (liquid/gas) time projection chamber. The cryostat is housed in a water tank ten meters high and ten meters in diameter, shown on the left in the picture. This water tank shields the experiment from ambient radioactivity. A three-story service building, shown on the right in the picture, houses the systems required for handling, cooling and purification of the xenon as well as electronics and computing required for data taking. First filling with liquid xenon is expected in 2014.
