Helium-Xenon mixtures to improve topological signature in high pressure gas Xenon TPCs
R. Felkai, F. Monrabal, D. Gonzalez-DÃaz +72
Within the framework of xenon-based double beta decay experiments, we propose the possibility to improve the background rejection of an electroluminescent Time Projection Chamber (…
Calibration of the NEXT-White detector using decays
G. MartÃnez-Lema, J. A. Hernando Morata, B. Palmeiro +74
The NEXT-White (NEW) detector is currently the largest radio-pure high-pressure xenon gas time projection chamber with electroluminescent readout in the world. NEXT-White has been…
Sensitivity of the NEXT experiment to Xe-124 double electron capture
G. MartÃnez-Lema, M. MartÃnez-Vara, M. Sorel +88
Double electron capture by proton-rich nuclei is a second-order nuclear process analogous to double beta decay. Despite their similarities, the decay signature is quite different,…
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…
Radiogenic backgrounds in the NEXT double beta decay experiment
NEXT Collaboration, P. Novella, B. Palmeiro +88
Natural radioactivity represents one of the main backgrounds in the search for neutrinoless double beta decay. Within the NEXT physics program, the radioactivity-induced background…
Electron drift properties in high pressure gaseous xenon
NEXT Collaboration, A. Simón, R. Felkai +73
Gaseous time projection chambers (TPC) are a very attractive detector technology for particle tracking. Characterization of both drift velocity and diffusion is of great importance…
