Development and test in liquid argon of the light readout system for the ArDM experiment


Boccone, V (2009). Development and test in liquid argon of the light readout system for the ArDM experiment. In: CIPANP 2009 - 10th International Conference on the Intersections of Particle and Nuclear Physics, San Diego, Calif., US, 26 May 2009 - 31 May 2009, 280-283.

Abstract

ArDM is a new-generation WIMP detector which will measure simultaneously light and charge from scintillation and ionization of liquid argon. Our goal is to construct, characterize and operate a 1 ton liquid argon (LAr) underground detector. The project relies on the read out of the VUV scintillation light and on the extraction of the electrons produced by ionization from the liquid into the gas phase of the detector. The light has to be converted with wavelength shifters such as TetraPhenyl Butadiene in order to be detected by photomultipliers with bialkali photocathodes. I describe the light readout system and the tests of the prototype with liquid argon in the full size detector. ©2009 American Institute of Physics

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
