EXO : the Enriched Xenon Observatory for Double Beta Decay
نویسنده
چکیده
EXO is a search for neutrinoless double beta decay in 136 Xe. An active R&D program for a 10 ton, enriched 136 Xe liquid phase detector is now underway. Current research projects are: decay product extraction, Xe purity studies, energy resolution studies, and Ba+ ion laser-tagging. Half lives of up to 5.0x10 28 yr will be ultimately probed, corresponding to a sensitivity to Majorana neutrino masses ≥ 10meV.

A linear RFQ ion trap for the Enriched Xenon Observatory
The design, construction, and performance of a linear radio-frequency ion trap (RFQ) intended for use in the Enriched Xenon Observatory (EXO) are described. EXO aims to detect the neutrinoless double-beta decay of 136Xe to 136Ba. To suppress possible backgrounds EXO will complement the measurement of decay energy and, to some extent, topology of candidate events in a Xe filled detector with the...
متن کاملClassification of Induction Signals for the EXO-200 Double Beta Decay Experiment
THE EXO-200 experiment searches for double beta decay in Xenon-136, in both the 2-neutrino and 0-neutrino modes. The EXO-200 detector has a set of wires that collect all charge released within the detector volume. Aside from the double beta decay events that occur within the detector, there are other types of background events that can release charge, such as compton scattering. Some of these t...

We report on the final results of a series of experiments on double decay of Te carried out with an array of twenty cryogenic detectors. The set-up is made with crystals of TeO2 with a total mass of 6.8 kg, the largest operating one for a cryogenic experiment. Four crystals are made with isotopically enriched materials: two in Te and two others in Te . The remaining ones are made with natural t...
متن کاملEnergy Measurement in EXO-200 using Boosted Regression Trees
The EXO-200 experiment uses a Liquid Xenon (LXe) time projection chamber (TPC) to search for neutrinoless-double beta decay(0νββ), an extremely rare hypothetical decay that would indicate the Majorana nature of neutrinos.[1, 2, 3] The EXO-200 experiment has been taking data for over 2 years and has published one of the most sensitive limits on 0νββ half-life. Events deposit energy in the LXe th...
