Microscopic simulation of xenon-based optical TPCs in the presence of molecular additives
C. D. R. Azevedo, D. Gonzalez-Diaz, S. F. Biagi +67
We introduce a simulation framework for the transport of high and low energy electrons in xenon-based gaseous optical time projection chambers (OTPCs). The simulation relies on ele…
Radon and material radiopurity assessment for the NEXT double beta decay experiment
S. Cebrián, J. Pérez, I. Bandac +67
The Neutrino Experiment with a Xenon TPC (NEXT), intended to investigate the neutrinoless double beta decay using a high-pressure xenon gas TPC filled with Xe enriched in 136Xe at…
Micro-physics simulations of columnar recombination along nuclear recoil tracks in high-pressure Xe gas for directional dark matter searches
Y. Nakajima, A. Goldschmidt, M. Long +3
Directional sensitivity is one of the most important aspects of WIMP dark matter searches. Yet, making the direction of nuclear recoil visible with large target masses is a challen…
Measurement of scintillation and ionization yield with high-pressure gaseous mixtures of Xe and TMA for improved neutrinoless double beta decay and dark matter searches
Y. Nakajima, A. Goldschmidt, H. S. Matis +3
Liquid Xe TPCs are among the most popular choices for double beta decay and WIMP dark matter searches. Gaseous Xe has intrinsic advantages when compared to Liquid Xe, specifically,…
An improved measurement of electron-ion recombination in high-pressure xenon gas
NEXT Collaboration, L. Serra, M. Sorel +64
We report on results obtained with the NEXT-DEMO prototype of the NEXT-100 high-pressure xenon gas time projection chamber (TPC), exposed to an alpha decay calibration source. Comp…
Results of the material screening program of the NEXT experiment
T. Dafni, V. Alvarez, I. Bandac +67
The 'Neutrino Experiment with a Xenon TPC (NEXT)', intended to investigate neutrinoless double beta decay, requires extremely low background levels. An extensive material screening…
