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…
Ion Transport on Phased Radiofrequency Carpets in Xenon Gas
E. Dey, B. J. P. Jones, Y. Mei +7
We present the design and performance of a four-phased radiofrequency (RF) carpet system for ion transport in high-pressure xenon gas. The RF carpet, designed with a 160 m pitc…
Measurement of Energy Resolution with the NEXT-White Silicon Photomultipliers
T. Contreras, B. Palmeiro, H. Almazán +107
The NEXT-White detector, a high-pressure gaseous xenon time projection chamber, demonstrated the excellence of this technology for future neutrinoless double beta decay searches us…
Fluorescence Imaging of Individual Ions and Molecules in Pressurized Noble Gases for Barium Tagging in Xe
NEXT Collaboration, N. Byrnes, E. Dey +112
The imaging of individual Ba ions in high pressure xenon gas is one possible way to attain background-free sensitivity to neutrinoless double beta decay and hence establish…
