Background Discrimination for Neutrinoless Double Beta Decay in Liquid Xenon Using Cherenkov Light
Jason Philip Brodsky, Samuele Sangiorgio, Michael Heffner +1
Neutrinoless double beta decays in liquid xenon produce a significant amount of Cherenkov light, with a photon number and angular distribution that distinguishes these events from…
Study of the loss of Xenon Scintillation in Xenon-Trimethylamine Mixtures
A. M. F. Trindade, J. Escada, A. F. V. Cortez +75
This work investigates the capability of TMA ((CH3)3N) molecules to shift the wavelength of Xe VUV emission (160-188 nm) to a longer, more manageable, wavelength (260-350 nm). Ligh…
Initial results on energy resolution of the NEXT-White detector
J. Renner, P. Ferrario, G. Martínez-Lema +77
One of the major goals of the NEXT-White (NEW) detector is to demonstrate the energy resolution that an electroluminescent high pressure xenon TPC can achieve for high energy track…
Study of Silicon Photomultiplier Performance in External Electric Fields
X. L. Sun, T. Tolba, G. F. Cao +149
We report on the performance of silicon photomultiplier (SiPM) light sensors operating in electric field strength up to 30 kV/cm and at a temperature of 149K, relative to their per…
Electroluminescence TPCs at the thermal diffusion limit
C. A. O. Henriques, C. M. B. Monteiro, D. González-Díaz +78
The NEXT experiment aims at searching for the hypothetical neutrinoless double-beta decay from the Xe isotope using a high-purity xenon TPC. Efficient discrimination of t…
VUV-sensitive Silicon Photomultipliers for Xenon Scintillation Light Detection in nEXO
A. Jamil, T. Ziegler, P. Hufschmidt +140
Future tonne-scale liquefied noble gas detectors depend on efficient light detection in the VUV range. In the past years Silicon Photomultipliers (SiPMs) have emerged as a valid al…
