Demonstration of Sub-Percent Energy Resolution in the NEXT-100 Detector
NEXT Collaboration, M. Pérez Maneiro, M. Martínez-Vara +111
NEXT-100 is a high-pressure xenon time projection chamber with electroluminescent amplification, designed to operate with up to approximately 70.5 kg at 13.5 bar. It is the most re…
High Voltage Delivery and Distribution for the NEXT-100 Time Projection Chamber
NEXT Collaboration, C. Adams, H. Almazán +105
A critical element in the realization of large liquid and gas time projection chambers (TPCs) is the delivery and distribution of high voltages into and around the detector. Such e…
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…
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 pitch…
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…
Design, characterization and installation of the NEXT-100 cathode and electroluminescence regions
NEXT Collaboration, K. Mistry, L. Rogers +107
NEXT-100 is currently being constructed at the Laboratorio Subterráneo de Canfranc in the Spanish Pyrenees and will search for neutrinoless double beta decay using a high-pressure…
NEXT-CRAB-0: A High Pressure Gaseous Xenon Time Projection Chamber with a Direct VUV Camera Based Readout
NEXT Collaboration, N. K. Byrnes, I. Parmaksiz +116
The search for neutrinoless double beta decay () remains one of the most compelling experimental avenues for the discovery in the neutrino sector. Electroluminescent gas-phas…
A Compact Dication Source for Ba Tagging and Heavy Metal Ion Sensor Development
K. E. Navarro, B. J. P. Jones, J. Baeza-Rubio +107
We present a tunable metal ion beam that delivers controllable ion currents in the picoamp range for testing of dry-phase ion sensors. Ion beams are formed by sequential atomic eva…
Reflectance and fluorescence characteristics of PTFE coated with TPB at visible, UV, and VUV as a function of thickness
