Detection of scintillation light in noble gases with wavelength-shifting optical fibers
S. R. Soleti, S. Torelli, G. MartÃnez-Lema +110
Wavelength-shifting (WLS) techniques enable particle detectors based on noble gases, whose scintillation light is predominantly emitted in the vacuum-ultraviolet. We investigate WL…
First results of the NEXT-100 detector using Kr decays
NEXT Collaboration, G. MartÃnez-Lema, C. Hervés Carrete +113
The NEXT collaboration is investigating the double beta decay of Xe using high-pressure gas electroluminescent time projection chambers, which provide excellent energy reso…
The NEXT-100 Detector
NEXT Collaboration, C. Adams, H. Almazán +114
The NEXT collaboration is dedicated to the study of double beta decays of Xe using a high-pressure gas electroluminescent time projection chamber. This advanced technology…
Electroluminescence and charge multiplication in liquid xenon with a VCC-like Microstrip Plate
Gonzalo MartÃnez-Lema, Vitaly Chepel, Amos Breskin
We report on the first observation of electroluminescence and charge amplification with a Virtual Cathode Chamber (VCC) microstrips plate immersed in liquid xenon. Both were observ…
Performance of an Optical TPC Geant4 Simulation with Opticks GPU-Accelerated Photon Propagation
NEXT Collaboration, I. Parmaksiz, K. Mistry +113
We investigate the performance of Opticks, a NVIDIA OptiX API 7.5 GPU-accelerated photon propagation tool compared with a single-threaded Geant4 simulation. We compare the simulati…
Reconstructing neutrinoless double beta decay event kinematics in a xenon gas detector with vertex tagging
NEXT Collaboration, M. MartÃnez-Vara, K. Mistry +108
If neutrinoless double beta decay is discovered, the next natural step would be understanding the lepton number violating physics responsible for it. Several alternatives exist bey…
